44 Bootis A, B and C

This system is also known as i Bootis.  It’s about 42 light years from Sol and is made up of an F9V star and two G2V stars.  B and C are far too close to each other to have habitable planets -- not much farther from each other than Earth is from the Moon, in fact.  The pair don’t come closer to A than 70 AU, though, so it could still have something we could use.  However, the system is not much more than a billion and a half years old.
