Lupus-TR-3 is a star located in the southern constellation Lupus. It has an apparent magnitude of 17.4, [2] making it visible only in power telescopes. Its distance is not well known, but it is estimated to be roughly 2,000 parsecs away from the Solar System. [2]
Lupus-TR-3 has a stellar classification of K1 V, [3] indicating that it is an ordinary K-type main-sequence star. It has 87% the mass of the Sun and 82% the radius of the Sun. It radiates at an effective temperature of 5,000 K. [2]
Lupus-TR-3 b is an exoplanet discovered in 2007 by personnel from the Center for Astrophysics | Harvard & Smithsonian using the transit method. It 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. [2]
