Planetary System
In 1989, a possible brown dwarf or planet was found orbiting HD 114762A by David Latham using Doppler spectroscopy. This object wasn’t fully confirmed until 1996 by Geoffrey Marcy. If it is a planet it is one of the most massive found to date, at the very least 11 Jupiter masses. However, the mass will be known more accurately when the inclination is finally determined. This object is very likely to be a brown dwarf or less likely a red dwarf with upper-mass limit 145 Jupiter masses. It orbits at about the same mean distance and has about the same time of revolution around the central star as Mercury, although HD 114762 b's orbit is eccentric.

Famous quotes containing the words planetary and/or system:
“We cannot cheat on DNA. We cannot get round photosynthesis. We cannot say I am not going to give a damn about phytoplankton. All these tiny mechanisms provide the preconditions of our planetary life. To say we do not care is to say in the most literal sense that “we choose death.””
—Barbara Ward (1914–1981)
“Television is an excellent system when one has nothing to lose, as is the case with a nomadic and rootless country like the United States, but in Europe the affect of television is that of a bulldozer which reduces culture to the lowest possible denominator.”
—Marc Fumaroli (b. 1932)
