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 Center for Astrophysics | Harvard & Smithsonian observing at the Siding Spring Observatory in Australia, by the transit method.

Semi-major axis | 0.0464 ± 0.0007 AU (6,940,000 ± 100,000 km) |
| Eccentricity | 0 |
Orbital period (sidereal) | 3.91405 ± 4e-5 d |
| Inclination | 88.3+1.3−0.8 |
Time of periastron | 2453887.0818 |
| Semi-amplitude | 114 ± 25 |
| Star | Lupus-TR-3 |
| Physical characteristics | |
Mean radius | 0.89 ± 0.07 RJ |
| Mass | 0.81 ± 0.18 MJ |
Mean density | 1,400 ± 400 kg/m3 (2,360 ± 670 lb/cu yd) |
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.[1]

Lupus-TR-3 b ist ein potentieller Exoplanet im Sternbild Lupus (Wolf). Die Entdeckung des Objektes geht auf die Beobachtung eines Helligkeitsabfalls einer stellaren Lichtquelle zurück (Weldrake et al. 2008). Die Entdeckung wurden durch Messungen der Radialgeschwindigkeit unterstützt, die Umlaufdauer zu 3,914 Tagen bestimmt.- [en] Lupus-TR-3b
