Talk:Exoplanet orbital and physical parameters

Comments
This article really seems redundant in view of the much larger article on extrasolar planet, and so I will plan to nominate it for deletion unless someone objects. Kevin Nelson (talk) 05:57, 23 April 2010 (UTC)
 * Some notability for the term can be established, as it has been mentioned in several scientific papers. Personally I would recommend a merge/redirect of the term into the extrasolar planet article.&mdash;RJH (talk) 21:10, 22 May 2010 (UTC)
 * I would suggest redirecting to astrobiology instead. Michaeltyrmarskell (talk) 11:48, 5 October 2010 (UTC)
 * I've moved all relevant information.
 * As previously mentioned, the notability of the term can be established, as it is now continually being mentioned in several scientific papers. It is a young field that is focused on Exoplanets, yet it is an integrated science that comprises Astrobiology, Astrophysics and Astronomy. It is a unique field that deserves further recognition. The universe is expanding. We need to expand our minds, too. Let us keep this wikipedia entry on Exoplanetology page and see where it takes us. Let's see how it inspires the next generation. — Preceding unsigned comment added by Metapsyche (talk • contribs) 15:18, 22 March 2011 (UTC)

Orphaned references in Exoplanetology
I check pages listed in Category:Pages with incorrect ref formatting to try to fix reference errors. One of the things I do is look for content for orphaned references in wikilinked articles. I have found content for some of Exoplanetology's orphans, the problem is that I found more than one version. I can't determine which (if any) is correct for this article, so I am asking for a sentient editor to look it over and copy the correct ref content into this article.

Reference named "footnoteD" in group "lower-alpha": From Exoplanet: About 1/4 of stars are GK Sun-like stars. The number of stars in the galaxy is not accurately known, but assuming 200 billion stars in total, the Milky Way would have about 50 billion Sun-like (GK) stars, of which about 1 in 5 (22%) or 11 billion would be Earth-sized in the habitable zone. Including red dwarfs would increase this to 40 billion. From Solar System: The mass of the Solar System excluding the Sun, Jupiter and Saturn can be determined by adding together all the calculated masses for its largest objects and using rough calculations for the masses of the Oort cloud (estimated at roughly 3 Earth masses), the Kuiper belt (estimated at roughly 0.1 Earth mass) and the asteroid belt (estimated to be 0.0005 Earth mass) for a total, rounded upwards, of ~37 Earth masses, or 8.1% of the mass in orbit around the Sun. With the combined masses of Uranus and Neptune (~31 Earth masses) subtracted, the remaining ~6 Earth masses of material comprise 1.3% of the total orbiting mass. From Planetary system: Converting log scale [m/H] to multiple of solar metallicity: [(10−0.6 ≈ 1/4), (100.5 ≈ 3)] From Planet: Both once referred to as "planets" by Cassini in his An Extract of the Journal Des Scavans.... The term "satellite" had already begun to be used to distinguish such bodies from those around which they orbited ("primary planets"). 

Reference named "footnoteA" in group "lower-alpha": From Extraterrestrial life: For the purpose of this 1 in 5 statistic, "Sun-like" means G-type star. Data for Sun-like stars wasn't available so this statistic is an extrapolation from data about K-type stars From Exoplanet: For the purpose of this 1 in 5 statistic, "Sun-like" means G-type star. Data for Sun-like stars was not available so this statistic is an extrapolation from data about K-type stars From Planet: This definition is drawn from two separate IAU declarations; a formal definition agreed by the IAU in 2006, and an informal working definition established by the IAU in 2001/2003 for objects outside of the Solar System. The official 2006 definition applies only to the Solar System, whereas the 2003 definition applies to planets around other stars. The extrasolar planet issue was deemed too complex to resolve at the 2006 IAU conference.</li> </ul>

Reference named "footnoteB" in group "lower-alpha":<ul> <li>From Exoplanet: For the purpose of this 1 in 5 statistic, Earth-sized means 1–2 Earth radii</li> <li>From Solar System: According to current definitions, objects orbiting the Sun are classified dynamically and physically into three categories: planets, dwarf planets, and small Solar System bodies. A planet is any body orbiting the Sun whose mass is sufficient for gravity to have pulled it into a (near-)spherical shape and that has cleared its immediate neighbourhood of all smaller objects. By this definition, the Solar System has eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Because it has not cleared its neighbourhood of other Kuiper belt objects, Pluto does not fit this definition. Instead, Pluto is a dwarf planet, a body orbiting the Sun that is massive enough to be made near-spherical by its own gravity but that has not cleared planetesimals from its neighbourhood and is also not a satellite. In addition to Pluto, the IAU has recognized four other dwarf planets in the Solar System: Ceres, Haumea, Makemake, and Eris. Other objects commonly (but not officially) treated as dwarf planets include, Sedna, Orcus, and Quaoar. In a reference to Pluto, other dwarf planets orbiting in the trans-Neptunian region are sometimes called "plutoids". The remaining objects orbiting the Sun are known as small Solar System bodies. </li> <li>From Planet: Referred to by Huygens as a Planetes novus ("new planet") in his Systema Saturnium</li> </ul>

I apologize if any of the above are effectively identical; I am just a simple computer program, so I can't determine whether minor differences are significant or not. AnomieBOT ⚡ 01:56, 29 July 2016 (UTC)

Split up List of exoplanets
