Lupus-TR-3 is a star located in the southern constellation Lupus. It has an apparent magnitude of 17.4, 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.

Physical characteristics

Lupus-TR-3 has a stellar classification of K1 V, 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.

Planetary system

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/cm. 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.
