XO-1 has a mass and radius similar to the Sun. In 2006 the extrasolar planet XO-1b was discovered orbiting XO-1 by the transit method using the XO Telescope.[4] Planetary systemThe XO Project is an international team of professional and amateur astronomers which discovered the Jupiter-sized planet orbiting around XO-1. The team, led by Peter McCullough of the Space Telescope Science Institute in Baltimore, includes four amateur astronomers from North America and Europe. The planet was confirmed using the Harlan J. Smith Telescope and Hobby-Eberly Telescope at McDonald Observatory of the University of Texas.[4] An independent confirmation of the planet was made by the Wide Angle Search for Planets project.[28] Further observations with the NICMOS instrument on board the Hubble Space Telescope detected the presence of water vapor, methane, and carbon dioxide in the atmosphere of XO-1b.[29] However an independent reinvestigation of the same data was unable to reproduce these results.[30] {{OrbitboxPlanet begin| table_ref = [32] }}{{OrbitboxPlanet | exoplanet = b | mass = {{val|0.907|0.022}} | semimajor = {{val|0.04914|0.00045}} | period = {{val|3.94150514|(20)}} | eccentricity = {{val|0.019|p=<}} | inclination = {{val|88.84|0.22}} | radius = {{val|1.199|0.017}} }}{{Orbitbox end}} See also
