Notes

Can someone add the age and mass off this star aswell as luminosity vs our sun to the data box --JSon94 (talk) 00:05, 28 January 2015 (UTC)

Should note the Mike Wall Space.com ref is the primary source; whereas the Yahoo news ref source is a copy of the original Mike Wall ref - in any case - Enjoy! :) Drbogdan (talk) 00:56, 28 January 2015 (UTC)

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. 24.79.36.94 (talk) 21:40, 2 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)

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)
