The planet was discovered in 2007 by personnel from the [[Harvard-Smithsonian Center for Astrophysics|Center for Astrophysics {{!}} Harvard & Smithsonian]] 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/cm<sup>3</sup>. This planet is a typical “[[Hot Jupiter]]” as it orbits at 0.0464 [[Astronomical Unit|AU]] distance from the star, taking 3.9 days to [[orbital revolution|orbit]]. It is currently the faintest ground-based detection of a transiting planet.<ref name="disc">{{ cite journal | url=http://www.iop.org/EJ/article/1538-4357/675/1/L37/22389.html | title=Lupus-TR-3b: A Low-Mass Transiting Hot Jupiter in the Galactic Plane? | author=Weldrake | journal= The Astrophysical Journal Letters | date=2008 | volume=675 | issue=1 | pages=L37–L40 | doi=10.1086/529519 | last2=Bayliss | first2=Daniel D.
