10 Canum Venaticorum
Estimates of this star’s age range from 4.9 billion to 14.5 billion -- the latter figure would make it about as old as the universe! So it’s probably not quite that elderly. It’s a G0V star, 56.7 light years away, with a metallicity around 30% of Sol’s.
Rho Coronae Borealis
This star is 56.8 light years from Sol. It’s a G0V yellow dwarf, like our sun but older at between 7.4 and 12.1 billion years. It has a dust disk similar to our Kuiper belt and at least one companion, which may be a super-Jovian planet or a dwarf star. Metallicity is around 60% of Sol.
