XO-3
XO-3 is a star 670 light-years (210 parsecs) away in the constellation Camelopardalis. The star has a magnitude of 10 and is not visible to the naked eye but is visible through a small telescope. A search for a binary companion star using adaptive optics at the MMT Observatory was negative.
In 2007, the gas giant exoplanet XO-3b was discovered by the XO Telescope using the transit method. This object may be classified as a brown dwarf because of its high mass, near the ~13 MJ limit for deuterium fusion. The planetary orbit is misaligned with the stellar rotation, which is unusual for such a massive planet. The misalignment may be due to an undetected companion star.
