Lupus-TR-3b is a potential exoplanet in the constellation Lupus (Wolf). The discovery of the object goes back to the observation of a decrease in brightness of a stellar light source (Weldrake et al. 2008). The discovery was supported by measurements of the radial velocity, the orbit duration determined to be 3,914 days .
With the help of high-resolution images, it was determined after the discovery that the light source Lupus-TR-3 , which was initially mistaken for a single star and which showed the observed decrease in brightness, was actually at least six, possibly seven, separate objects. The question of which of the observed stars shows the transit is the subject of ongoing investigations (as of spring 2010). The originally derived values for the possible exoplanet (0.8 Jupiter masses and 0.9 Jupiter radii) are no longer valid.
