79 Ceti b planet. Artwork of the extrasolar planet 79 Ceti b (centre right) on the horizon of its moon (foreground). The parent star 79 Ceti (or HD 16141),is seen at upper right. 79 Ceti is a Sun- like star which lies 117 light years from Earth in the constellation Cetus. Two rows of sunspots are seen on its surface. 79 Ceti b is thought to be similar to Saturn. It has a mass about 70% that of Saturn (68 times that of Earth). It orbits 52 million kilometres from its star (a third of the Earth-Sun distance),taking 76 days to complete an orbit. The planet's presence was inferred in March 2000 after observing the star's wobble as it moved through space,caused by the orbiting planet | |
