The star’s low metallicity and fairly high space velocity suggest that KOI-4878 is older than the Sun.

But I don't know how to calculate an estimation for the age.

KOI-4878 data on Simbad: http://simbad.u-strasbg.fr/simbad/sim-id?Ident=KOI-4878&NbIdent=1&Radius=2&Radius.unit=arcmin&submit=submit+id

  • $\begingroup$ Hi Alexander Martin - welcome to Physics.SE! I see that you have cross-posted this on the Astronomy.SE site as well. Although it is on topic in both places, it is frowned upon to post the same question on multiple sites. I'd recommend picking one to keep open and deleting the other. And when you get a chance, check out our Tour page! $\endgroup$ – tpg2114 Oct 2 at 12:40
