HD 93083 b
HD 93083 b is an extrasolar planet orbiting the K-type subgiant 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.
The planet HD 93083 b is named Melquíades. The name was selected in the NameExoWorlds campaign by Colombia, during the 100th anniversary of the IAU. Melquíades is a fictional character in the novel One Hundred Years of Solitude that walks around Macondo.
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.
