Epsilon Eridani c
Sub-Giant

Comments

Epsilon Eridani c was inferred by computer analysis of its parent star's dust disk. If it exists, it is likely to orbit its parent star in an eccentric pluto-like orbit. This planet's orbital distance was calculated assuming a period of 260 years and a mass of 0.8 solar masses for the parent star.
