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)

Wall, Mike (27 January 2015). "Found! 5 Ancient Alien Planets Nearly As Old As the Universe". Space.com. Retrieved 27 January 2015.

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:

The Kepler-444 planetary system
Companion (in order from star)	Mass	Semimajor axis (AU)	Orbital period (days)	Eccentricity	Inclination	Radius
Kepler-444b	—	0.04178	3.60001053	0.16	88°	0.4 R_🜨
Kepler-444c	—	0.04881	4.5458841	0.31	88.2°	0.497 R_🜨
Kepler-444d	—	0.06	6.189392	0.18	88.16°	0.53 R_🜨
Kepler-444e	—	0.0696	7.743493	0.1	89.13°	0.546 R_🜨
Kepler-444f	—	0.0811	9.740486	0.29	87.96°	0.741 R_🜨

The Kepler-444 planetary system
Companion (in order from star)	Mass	Semimajor axis (AU)	Orbital period (days)	Eccentricity	Inclination	Radius
Mercury	0.055 M_🜨	0.387	87.9691	0.205630	7.005°	0.3829 R_🜨
Venus	0.815 M_🜨	0.723	224.701	0.0067	3.39458°	0.9499 R_🜨
Earth	1 M_🜨	1.00	365.256	0.01671022	7.155°	1 R_🜨
Mars	0.107 M_🜨	1.524	686.971	0.0935	5.65°	0.533 R_🜨

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)

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)
