}}{{Starbox end}}XO-3 is a star 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.[4] A search for a binary companion star using adaptive optics at the MMT Observatory was negative.[23]

Planetary system

In 2007 the gas giant exoplanet XO-3b was discovered by the XO Telescope using the transit method. This object may be classed as brown dwarf because of its high mass.[4]
