HD 70642

== Planetary system ==
A long period planet companion to HD 70642 was announced in 2003. This planet orbits in a circular orbit (e=0.034) at 3.232 AU.〔 The star is so like to Sol that its habitable zone is in the same place (~ 1 AU). The jovian ensures the stability of an Earth-mass planet at 1 AU. This system is one of the most similar in conditions to our solar system than any other currently known planetary systems.
