HD 38529 b [SEP] constellation
HD 38529 b
HD 38529 b is an extrasolar planet approximately 138 light years away in the constellation of Orion. This planet was discovered in 2000. Because of its mass, it is likely that it is a gas giant.
the Hipparcos satellite gave a best fit inclination of 160° and a true mass 37 times that of Jupiter, turning this planet into a brown dwarf. Further study of the system using Hubble Space Telescope astrometry revised the mass of HD 38529 c downwards to 17.7 Jupiter masses and suggested the presence of an additional planet, orbiting in the gap between HD 38529 b and c. The possible third planet was refuted after additional radial velocity measurements were collected.
