==Planetary system== 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 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.
