COROT-1 is a yellow dwarf main sequence star similar to our Sun. The star is located approximately 1,560 light-years away in the constellation of Monoceros. The apparent magnitude of this star is 13.6, which means it is not visible to the naked eye; however, it can be seen through a medium-sized amateur telescope on a clear, dark night. The first exoplanet discovered in the course of the COROT mission orbits this star; it is considered to be a "hot Jupiter," and is approximately as massive as the planet Jupiter itself.
The designation "COROT" is a result of its observation by the French-directed Convection, Rotation, and Planetary Transits mission, which was launched late December 2006 with one goal involving the search for exoplanets by measuring the varying brightness of candidate stars when transited by any present exoplanets; CoRoT's second goal pertains to the study of the interiors of stars, which is done by analyzing the characteristics and behavior of light released from the star. The numerical designation was assigned because the first exoplanet discovered by the CoRoT telescope was found in orbit of this star. COROT-1 does not have a common or colloquial name like that of Sirius or Procyon.
COROT-1 is a G-type star, meaning the light it emits is similar to that of the Sun's. Likewise, the star is of nearly the same temperature and mass of the Sun. At an apparent magnitude of approximately +13.6, doubly dimmer than the dimmest star visible with the naked eye, COROT-1 cannot be seen from Earth without magnification apparatus.
