HD 70642 [SEP] constellation
HD 70642
HD 70642 is a yellow dwarf star in the constellation of Puppis located 92 light years away. This star has about the same mass and radius as the Sun, is slightly cooler and less luminous, and is richer in abundance of iron relative to hydrogen.
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 Sol that its habitable zone is in the same place (
HD 47186 b
HD 47186 b is a “hot Neptune” extrasolar planet located approximately 123 light years away in the constellation of Canis Major, orbiting the star HD 47186. This planet has a minimum mass of 22.78 times that of Earth and orbits very close to the star at a similar distance from the star as 51 Pegasi b is from 51 Pegasi. As in consequence, it takes 4.0845 days to complete an orbit with an eccentricity of 0.038, which is similar to the 5.66 year-period planet HD 70642 b.
