description HD 130322 b Overview
HD 130322 b is a giant exoplanet orbiting the K-type star HD 130322. It was discovered through stellar radial-velocity measurements and announced in 1999 by a team led by Michel Mayor and Didier Queloz's collaborator Stéphane Udry. The planet completes an orbit in about 10.7 days, so it is classified as a hot Jupiter or another short-period giant planet. Its orbit is not perfectly circular, although its eccentricity is modest compared with some other exoplanets.
