    planets around other stars

    planets around a pulsar the first confirmed discovery of earth and jupiter-sized planets around any star.... but how did they get to be around a star that supernovaed? are they debris?

    in October '95 the discovery of the first planet orbiting a solar-type star (51 Pegasi) was announced and confirmed.... and in Jan '96, the discovery of two other planets (both around sun-like stars) followed... the complete list:
