83 Leonis Bb, also catalogued as HD 99492 b or abbreviated 83 Leo Bb, is an extrasolar planet approximately 58 light-years away in the constellation of Leo (the Lion).
She is also a member of the planet search team led by Geoffrey Marcy looking for extrasolar planets.
Geoffrey W. Marcy (born September 29, 1954) is an American astronomer, who is currently Professor of Astronomy at the University of California, Berkeley, famous for discovering more extrasolar planets than anyone else, 70 out of the first 100 to be discovered, along with R. Paul Butler and Debra Fischer.
Using the radial velocity technique, the search for substellar companions has thus far failed to find a brown dwarf or extrasolar planet in the "hot zone" orbit around Kappa1 Ceti.
It depicts a massive interstellar colonization effort, involving hundreds of immense generation ships known as "holoships" carrying millions of humans to extrasolar planets.
Marcy confirmed Michel Mayor and Didier Queloz's discovery of the first extrasolar planet orbiting a Sun-like star—51 Pegasi b.
Soon after the discovery, separate teams led by David Charbonneau and Gregory W. Henry were able to detect a transit of the planet across the surface of the star making it the first known transiting extrasolar planet.
Soon after the discovery, separate teams, one led by David Charbonneau including Timothy Brown and others, and the other by Gregory W. Henry, were able to detect a transit of the planet across the surface of the star making it the first known transiting extrasolar planet.
In 1855, Captain W. S. Jacob of the East India Observatory in Madras found orbital anomalies in the binary star 70 Ophiuchi that he claimed are evidence of an extrasolar planet—the first exoplanet false alarm.
