- PSR_B1257+12_B abstract "PSR B1257+12 c (ex PSR B1257+12 B) is an extrasolar planet (approximately 980 light-years away) in the constellation of Virgo (the Virgin). PSR B1257+12B was the first planet ever discovered outside the Solar System, and is one of three objects known to be orbiting the pulsar PSR B1257+12, which it circles at a distance of 0.36 AU with an orbital period of approximately 66 days. The planet is over four times as massive as the Earth. Because planet B and planet C have very similar masses (as well as orbiting close to each other), they cause measurable perturbations in each other's orbits. As expected, perturbations were detected confirming that the planets were real. Accurate masses of the two planets, as well as their inclinations, were measured by calculating how much the planets interfere with each other.".
