The discovery of 51Pegb in 1995

On 6 October 1995 at a conference in Florence, Italy, the Swiss astronomers Michel Mayor and Didier Queloz made a sensational announcement: They had discovered the first planet orbiting another solar-type star. They had already celebrated at the Observatory of Haute-Provence in private in summer 1995, but wanted to make sure that they had eliminated all sources of error before presenting their discovery. The pioneering paper about “A Jupiter-mass companion to a solar-type star” was published on 23 November 1995 in the journal Nature.
