Finding minor-planet names in MPC-publications
Hi Renerpho, there is a tool that might assist you finding a specific name among the many Minor Planet Circulars (website). For example, MPC's object page for (4388) Jurgenstock displays the Reference page number (36126). The tool maps this number to the corresponding publishing date (28 September 1999), and from there on it's easy to find the corresponding M.P.C. For 4388 Jürgenstock, page 362 (M.P.C. 36126), the name has been published with an umlaut. Hope that was informative. R fassbind – talk  03:42, 15 February 2019 (UTC)

By the way, we both registered on Wikipedia just 12 days apart. What a coincidence! R fassbind – talk  03:47, 15 February 2019 (UTC)

Thank you, Rfassbind! I have since contacted the MPC, to ask why there are two conflicting names on the website. JPL finds the object when looking for Jurgenstock, but not Jürgenstock. I was informed that the page titles on both the MPC and JPL do not display umlauts by default. P.S. Nice coincidence about our Wikipedia age (even though I wasn't very active for the first few years). Renerpho (talk) 22:52, 15 February 2019 (UTC)

Thanks for the awesome image
This is a very useful image of the TNOs known today. Well done!



Thanks for contributing it to the emergent encyclopedia of human knowledge! N2e (talk) 18:10, 5 November 2019 (UTC)
 * Thank you! I plan to update it regularly as more objects/classifications become available. Renerpho (talk) 01:29, 6 November 2019 (UTC)

I have a second, related image. While the first one makes the resonances more apparent, the classifications (cubewano, scattered, etc) are more transparent in this one (IMO):

47171 Lempo image
Hi Renerpho, could you upload a processed Hubble image of the 47171 Lempo system with all three components resolved? The artice's is quite old and the third component of the Lempo system hasn't been discovered at the time, and I figured that you can help replace the old image with a better one since you've uploaded a processed image of. N rco0e (talk · contribs) 00:07, 15 November 2019 (UTC)
 * I can try, but the third component is difficult to resolve. Renerpho (talk) 11:04, 15 November 2019 (UTC)



Done. Renerpho (talk) 12:48, 15 November 2019 (UTC) An image with all three components resolved doesn't work well. I decided against it, instead adding an image to the section about the individual components.12:51, 15 November 2019 (UTC)

Name Apophis
Hi @Renerpho , I saw that you have removed my contributed info on the page |99942 Apophis for the name Apophis, Would you please explain the reason more here. --Aaqibacs1 (talk) 11:03, 22 July 2020 (UTC)


 * In fact, I did not remove everything; I kept your citation, moving it into the infobox.
 * The first sentence of an article's lead section is not the place to give background information about the etymology of the name. That is secondary information that either can be handled in a subsection, or further down in the lead if it is absolutely necessary information. See the Manual of Style for details.
 * The article you edited is about an asteroid, and the lead should begin with the one thing that 99942 Apophis is most notable for. That is the initial impact risk. Your addition would have been more suitable for the subsection about the name, further down the article. Renerpho (talk) 11:29, 22 July 2020 (UTC)
 * Alright, Thanks for the help, So, It could be added in the section "Discovery and naming", Right? Aaqibacs1 (talk) 13:08, 22 July 2020 (UTC)
 * That could work, yes. Renerpho (talk) 13:19, 22 July 2020 (UTC)

List of fugitives from justice who disappeared
Hi, I see that you added an entry to List of fugitives from justice who disappeared, good job! Do you think that you could help add some entries to lists like this? I would be very thankful for any help that I can get. Davidgoodheart (talk) 10:21, 16 January 2021 (UTC)
 * Thanks! I don't think I can do much to help you, unfortunately. My edit was specific to the Marsalek case, and I won't have time to work on lists like this more frequently. Renerpho (talk) 08:56, 28 January 2021 (UTC)

Thanks for your edit
... on the Sedna page. I wasn't sure how long the body spent in proximity to the sun, so your revert was in order and well explained in the edit. Thanks for the change, and the explanation. 92.12.199.159 (talk) 22:34, 27 January 2021 (UTC)

Lagrange-point img
Hi Renerpho,

I thought I'd ask you this since you helped with the Haumea-Neptune resonance imgs.

Is this image accurate?

From what I understand, the L4 and L5 points are indeed local maxima, and it's Coriolis effects that cause the orbital stability. But shouldn't the potential otherwise go up with further distance from the Sun? The way I'm reading this, it looks like the Sun exerts a gravitational repulsion once you get past the Lagrange points.

Also, our article states that L4 and L5 are gravitational wells -- but doesn't that imply local minima in the potential, not just stability? — kwami (talk) 08:20, 24 July 2021 (UTC)


 * This looks accurate. (Do we need a 3D version of that diagram though?) It shows the effective potential, which includes the centrifugal force. It is only the gravitational potential that increases with distance. We already have an image on Wiki Commons that explains the difference.

The stability (and "attracting" effect) of the L4/L5 points is due to the Coriolis effect, which can not be shown on a contour plot. So whether the effective potential has maxima or minima there doesn't necessarily tell you about the nature of those points. Note that this is explained in the section "Stability". Perhaps describing them as a simple gravity well is confusing, because neither the gravitational nor the effective potential are enough to explain their stability. Renerpho (talk) 10:12, 24 July 2021 (UTC)


 * Thanks. That makes sense. The img itself claimed it was gravitational potential, so I changed that. Also removed 'gravitational well' from the article. — kwami (talk) 17:49, 24 July 2021 (UTC)
 * If the article said "gravitational well" then that's definitely wrong. It should be "gravity well". Renerpho (talk) 17:54, 24 July 2021 (UTC)
 * My bad. It was 'gravity'. — kwami (talk) 17:58, 24 July 2021 (UTC)
 * All good then. :) Renerpho (talk) 17:59, 24 July 2021 (UTC)

Another question, if you don't mind. At Recombination (cosmology), we give Z and the age of the Universe at the time of the CMB. But we don't give the density or the size of the Universe at that time. Do we have any idea what those values might be? — kwami (talk) 03:38, 26 July 2021 (UTC)
 * We do. Size is easy, see Observable universe. The observable universe had a radius of about 42 million light-years at the time of the CMB, as the scale factor is given by $$\alpha(t)=\frac{1}{1+z}$$. Feel free to add that information to the recombination article. Density is more complicated, as you need to specify what kind of density you're talking about. The energy density of matter scales as $$\rho_{M}\sim{\frac{1}{{a}^{3}}}$$, just as volume scales as $$V(t)\sim{{a}^{3}}$$. Another good source may be, if you're looking for something to add to this article. Renerpho (talk) 11:13, 26 July 2021 (UTC)

Pardon my joining your conversation. Re "(Do we need a 3D version of that diagram though?)", I'm tempted to recreate my diagram as an STL. However, the equation I have gives the potential in x, y, z while I think it's better for vertices to be on equipotential lines so that the deep funnels' shape are better captured. Would you have an equation that gives x and y values for a given z? Thanks, cm&#610;&#671;ee&#9094;&#964;a&#671;&#954; 12:25, 24 October 2021 (UTC)

P.S. Please include in your reply so I'm aware of it. Thanks!

Hygiea
I thought I'd already added the symbol!

If it doesn't display correctly, it's because you don't have a supporting font installed. There's nothing wrong with the encoding. — kwami (talk) 22:57, 19 August 2021 (UTC)

I tried on my phone and laptop; neither display it correctly. So I assume I am not the only one. Do we absolutely need the symbol? Alternatively, I suggest to replace the error-prone unicode symbol with an image. Would that work? Renerpho (talk) 23:03, 19 August 2021 (UTC)

We should have both. An image is already there. But some will want to be able to copy the character. And for those who do have supporting fonts installed, I don't see why we shouldn't include it.

A lot of things on WP don't display well for ppl who don't have a lot of fonts installed, which is why we use e.g. IPA to format IPA transcriptions and have warnings that the page includes IPA and may not display properly for some people. Maybe I could try Unicode here. — kwami (talk) 23:54, 19 August 2021 (UTC)

(Nah, 2BF1 doesn't seem to make any difference. BTW, it doesn't display properly for me either. But it will for some people, and font support will improve over time.)

I appreciate the idea, but the display error is confusing. How about turning it into a note instead? Those that want the unicode will find it there, everyone else will not be confused by the weird symbols in the main article body. Renerpho (talk) 00:08, 20 August 2021 (UTC)

How's that? I moved the img into the text, with the character in parentheses after it. — kwami (talk) 06:49, 20 August 2021 (UTC)

I think that works, too. Renerpho (talk) 13:57, 20 August 2021 (UTC)

Varda
Hi Renerpho, I should have looked more carefully before I reverted your edit to Varda. The underlying problem is that Varda (disambiguation) is malplaced. I have listed it at WikiProject Disambiguation/Malplaced disambiguation pages, so it should be fixed soon. Thanks for fixing my mistake. Leschnei (talk) 23:08, 28 September 2021 (UTC)
 * No problem. Thanks! Renerpho (talk) 02:22, 29 September 2021 (UTC)
 * Just to clarify, it wasn't my edit that you had reverted, but someone else's. I am tagging, in case they have input. Renerpho (talk) 14:35, 29 September 2021 (UTC)


 * That was my doing. Another like that is Manwë (disambiguation). The problem with these is that the plain title was a section rd, which made it difficult to place a hat note for the dab page. — kwami (talk) 05:54, 29 September 2021 (UTC)
 * Thanks for the explanation. I'm trying to remember if I've ever seen a DAP hatnote under a section heading - probably. Leschnei (talk) 11:27, 29 September 2021 (UTC)


 * If it were under a section heading, I'd've left it alone. But it was a rd to an item in a table. It would be messy to put a hat note inside a table, if it's even possible. I didn't try experimenting. Perhaps there could be a table-spanning row above the entry for the hat note, and the anchor for the rd could be there. If you think that would be best in the case of Manwë to avoid TWODAB, that would be okay w me. A dab page was just the most straightforward option. — kwami (talk) 19:52, 29 September 2021 (UTC)
 * I agree that a hat note inside of a table sounds extremely cumbersome! A DAB page is just fine - it just needs to be swapped so that Varda is the DAB page and Varda (disambiguation) redirects to it. I have made the request and it should be taken care of soon.

Outing at Talk:Recursion
While I recognize that your recent addition at Talk:Recursion was well intended, it's very bad form to link accounts to individuals when they haven't done so themselves (see WP:OUTING). In this case, the edit request had already been dealt with on non-COI grounds, so it really wasn't necessary. The OP was removing the whole section, but I have opted instead to just remove your post; I hope that's all right with you, and I wouldn't object if you reinstated a version of your post that warned about COI without explicitly making the off-wiki connection. --JBL (talk) 14:21, 3 April 2022 (UTC)
 * Hello JBL. Thanks, that's alright with me! In hindsight, I recognize that my post was poorly done. Renerpho (talk) 18:14, 3 April 2022 (UTC)

Hello
Hi Renerpho,

Just wanted to say that I'm trying to contact anyone that I may of offended with my post. The reason I said 'fool', was because it was a foolish statement. I'm not going to explain my reasoning. It was actually a wonderful word, compared to what I wanted to use at the time. Nonetheless, just wanted to end on a somewhat better note. Sorry for the offense.

Best. Bringingthewood (talk) 05:29, 25 September 2023 (UTC)

Valuejet RfD
Hello! I had noticed this happen when it did, but wasn't able to comment on it at the time, but please in the future do not relist your own RfD discussions. WP:RELIST is a helpful tool which outlines the relisting guidelines. In general, relists should only happen after a minimum of 7 days have elapsed, and when the discussion needs an extra push to solidify consensus. These should only be done by uninvolved parties, but in this edit,, it seems that you relisted after only 3 on the discussion you started. Thank you for understanding!

Is 2002 MS4 in resonance?
Hi,

Since you made the rotating frame animation of 2002 MS4's orbital resonance in action, I'd like to ask about the accuracy of 2002 MS4's supposed resonance. My issue is that every paper I could find about 2002 MS4 classifies the object as a hot classical KBO, and makes no remark on the intermittent 18:11 resonance claimed by Lykawka 2007. The Lykawka 2007 paper is the only paper that claims and discusses this resonance, and it hasn't been formally disputed as far as I'm aware, so I'm not sure if this resonance is still true or not. What do you think? How should we handle this single claim of a resonance in the 2002 MS4 article, which is currently undergoing GA review?

P.S. The GA review needs a second opinion/additional review of how accurately the sources were used in the article. By any chance, would you mind helping out? Nrco0e (talk) 05:19, 6 January 2024 (UTC)


 * I'm sorry I didn't reply earlier (see the WP:WB on my user page). The resonance is intermittent, so I'm not surprised that nobody claims there's a resonance (because there isn't; that's what intermittent means). I also see no indication that anything has changed about that since 2007 (or since I reproduced it; which, if I remember correctly, included more recent orbital information than Lykawka could have had, while leading to the same result). This has been only 17 years ago, which really isn't a lot for such a distant orbit.
 * As far as the GA review is concerned, I'm currently not able to look at that (too much RL stuff, as I said). I'm sorry I can't help. Renerpho (talk) 23:37, 10 January 2024 (UTC)
