Distance
trying to find the distance to the star. Along with lumoinsity too. I have the other data added.JSon94 (talk) 01:01, 28 January 2015 (UTC)

just need luminosity it's a KO orange dwarf JSon94 (talk) 01:11, 28 January 2015 (UTC)

Is this system really unusual?
Both the compact planets and how close they orbit. How'd they manage to stay in such of compact system for 2x longer than our solar system? look how chaotic our solar system was. I feel this may be quite a discovery JSon94 (talk) 01:34, 28 January 2015 (UTC)
 * According to science paper, the most unusual thing about this system currently are the sizes of the planets. At the moment, systems most similar to this are Kepler-80, Kepler-32 and Kepler-33. --Artman40 (talk) 20:06, 28 January 2015 (UTC)
 * You could add another planetary system chart underneath of our own system for comparison. I find the eccentricities to be interesting, and a comparison would be enlightening. Something like this:

This star also appears to have 2 faint M dwarfs in orbit around it which makes it even stranger when you look at the planets. IMO this system needs some serious studyingJSon94 (talk) 23:32, 2 February 2015 (UTC)
 * it's too bad the article doesn't have some kind of comparison diagram, something more accurate than this: https://farm8.staticflickr.com/7308/16245011907_e7ee015ed8_o.png This fellow appeared to be doing some interesting ones, he would be the one to ask: https://commons.wikimedia.org/wiki/User:Icalanise 24.79.36.94 (talk) 01:57, 8 February 2015 (UTC)

I'd be very interested in taking a shot at calculating the Effective temperatures or just Irradiance received by these planets, and I've looked around and can't find anything on this being a trinary system. Where did you happen to read it had two companion stars? 24.79.36.94 (talk) 04:43, 8 February 2015 (UTC)

Illustration
Would it be useful to have a picture depicting the orbital configuration and sizes of planets? --Artman40 (talk) 13:32, 28 January 2015 (UTC)

I think this system deserves an illustration just as much as any other that has one. 24.79.36.94 (talk) 22:03, 2 February 2015 (UTC)

I was curious enough to plot the semi-major axis circles, and it makes me wonder how stable this system is considering some of the eccentricities: https://farm8.staticflickr.com/7308/16245011907_e7ee015ed8_o.png 24.79.36.94 (talk) 22:46, 2 February 2015 (UTC)

Binary star or not?
Discovery paper refers that this star has an M-dwarf companion. Does the paper tell if that's an optical double star or a gravitationally bound binary? --Artman40 (talk) 13:37, 28 January 2015 (UTC)

looks like it's a triple systemJSon94 (talk) 06:00, 2 February 2015 (UTC)

Tidal locking?
Does anyway know if these planets are all likely to be locked with one phase to the star?JSon94  23:44, 2 February 2015 (UTC)
