Tau Piscis Austrini and 6 Ceti

Tau Piscis Austrini

This F6V dwarf is 61.1 light years from us.  It could be anywhere from 2.5 to 5.4 billion years old.  Metallicity is very close to Sol’s, just a little bit higher.

6 Ceti

This is an F5V star located 61.6 light years from Sol.  It is probably between 4.3 and 5.9 billion years old.  Metallicity is only 40% of Sol’s.
