70 Virginis

A very old sunlike star which slowly becomes a red giant. In a highly excentric orbit it is accompanied by a giant planet of 7.4 times the mass of Jupiter in a distance of 0.258 - 0.602 AU. The orbit period is 116.7 days.

Despite its uncommon orbit moons around the planet could have evolved life theoretically. Unfortunately this won't survive the expansion of the star.

The star has also a dust disk similar to our Kuiper belt.
