Lupus-TR-3b is an extrasolar planet orbiting the star Lupus-TR-3 (a K-type main sequence star approximately 8,950 light-years away in the constellation Lupus). The planet was discovered in 2007 by personnel from the Harvard-Smithsonian Center for Astrophysics observing at the Siding Spring Observatory in Australia, by the transit method.
The planet has four-fifths the mass of Jupiter, nine-tenths the radius, and has density of 1.4 g/cm³. This planet is a typical “Hot Jupiter” as it orbits at 0.0464 AU distance from the star, taking 3.9 days to orbit. It is currently the faintest ground-based detection of a transiting planet.
