High Quality Content by WIKIPEDIA articles! XO-2b is an extrasolar planet orbiting the star XO-2 in the constellation Lynx. This planet was found by transit method in 2007 by Burkes et al. This was the second such planet found by the XO telescope. Like the types of planets found by transit method, it is a hot Jupiter – Jupiter-like planets that orbit very close to their stars; in this case, it suffers temperature of about 1200 K. The planet takes 2.6 days to orbit the star at the average distance of 0.0369 AU. The planet has mass of 57% of Jupiter and radius of 97% of Jupiter. The radius is relatively large for its mass, probably due to its intense heating from its nearby star that bloats the planet's atmosphere. The large radius for its mass gives a low density of 820 kg/m3.
