It has a magnitude of about 12 and cannot be seen with the naked eye but is visible through a small telescope.[4][14] Planetary systemThe exoplanet XO-5b was discovered by the XO Telescope using the transit method in 2008. This planet is classified as a hot jupiter.[4] A search for transit timing variations caused by additional planets was negative.[26] {{OrbitboxPlanet begin| table_ref = [14][28] }}{{OrbitboxPlanet | exoplanet = b | mass = 1.059 ± 0.028 | period = 4.1877545 ± 0.0000016 | semimajor = 0.0488 ± 0.0006 | eccentricity = 0 }}{{Orbitbox end}} See also
