Humanity took one step closer to answering these questions in October 1995 when it was announced that the star 51 Pegasi harbors at least one planet. In the above picture of 51 Peg the planet is not visible - it can only be detected by noticing small changes in the star's motion. Claims of planets orbiting other stars are rare, with perhaps the most credible pertaining to a neutron star - a star much different than the Sun . But new ground was broken when the planetary detection claimed around the normal Sun-like star 51 Peg was confirmed. Peg are caused by the telescope itself and are not related to the star or planet.
