United Kingdom, Telephone: +44 (0) 20 7432 1100 51 Pegasi B 51 Pegasi B has more gravity than earth which means things would have to adapt to Astronomers have discovered the presence of water molecules in the atmosphere surrounding the hot Jupiter 51 Pegasi b. 51 Pegasi B. led to thousands more extrasolar planets being found. The 51 Pegasi b Fellowship provides exceptional postdoctoral scientists with the opportunity to conduct theoretical, observational, and experimental research in planetary astronomy. We don’t know its radius, since we found it by measuring its effect on its star via gravity, but looking at other planets of its mass, it probably is slightly larger in radius than Jupiter (which is something like 10 times the radius of Earth). The discovery was made with the radial velocity method on a telescope at Observatoire de Haute-Provence in France and using the ELODIE spectrograph. In terms of mass, 51 Pegasi b is at least 150 times the mass of the Earth (our measuring method gives a minimum mass; this is likely within a factor of 2 of its real mass). Its orbital period would be about 2.0 yr. On October 6, 1995, Swiss astronomers Michel Mayor and Didier Queloz announced the discovery of an extrasolar planetorbiting 51 Pegasi named 51 Pegasi b.
