XO-2b, the second transiting extrasolar planet from the XO Project (McCullough et al. 2005), is approximately Jupiter-size and 0.6 Jupiter-mass with an orbital period of 2.6 days. The stellar host, XO-2, is a V=11.2, early K dwarf which is metal rich, [Fe/H]=+0.44. XO-2 has a high proper motion, 157 mas/yr, and has a common proper motion stellar companion with half arcmin separation. The two stars are nearly identical twins, with very similar spectra and apparent magnitudes. The global network of amateur and professional astronomers organized by the XO project confirmed the XO-2b transit light curve two days after being notified that it was a high-priority candidate, and radial velocities confirmed its planetary mass eight days after that.
