HD 93083 b is an extrasolar planet orbiting the star HD 93083 in Antlia constellation. It is probably much less massive than Jupiter, although only the minimum mass is known. The planet's mean distance from the star is about half that of Earth, and the orbit is slightly eccentric. This planet is another discovery by the HARPS search team.[2]
Stability analysis reveals that the orbits of Earth-sized planets located in HD 93083 b's Trojan points would be stable for long periods of time.[3]
