Epsilon Eridani

This is an orange sunlike star with at least one gaseous planet, Epsilon Eridani b. This has 1.5 times the mass of Jupiter and orbits its star every 6.85 years in a distance of 1.9 - 3.7 AU.

Furthermore it is encircled by two asteroid belts, with the planet in between. Between the outer asteroid belt and the comet belt are two more planets suspected. Epsilon Eridani would be a good candidate for alien life. But it is too young as if this life could be already highly developed.
