HD 103197 b (also known as HIP 57931 b) is an extrasolar planet which orbits the K-type main sequence star HD 103197, located approximately 170 light years away in the constellation Centaurus. This planet has at least one-tenth the mass of Jupiter and takes 48 days to orbit the star at a semimajor axis of 0.235 AU. Fitting the observational data with a Keplerian orbit leads to a solution with an insignificant eccentricity. This planet was announced by the Swiss-led HARPS team on October 19, 2009, together with 29 other planets.
