NGC 2423-3b is an extrasolar planet[1] approximately 2498 light-years away in the constellation of Puppis. The planet was announced in 2007 to be orbiting the red giant star NGC 2423-3 (which in turn is part of the NGC 2423 open cluster). The planet has a mass at least 10.6 times that of Jupiter. Only the minimum mass is known since the orbital inclination is not known, so it may instead be a brown dwarf.
This planet was discovered by Christophe Lovis and Michel Mayor in June 2007. Lovis had also found three Neptune-mass planets orbiting HD 69830 in May 2006, also in Puppis.
