... Astronomers have recently discovered about a dozen planets orbiting stars similar to the Sun. ... The Earth is the only known planet which has water in the liquid, solid and gaseous forms. ... A planet is termed "habitable" if it has surface liquid water. The presence of liquid water depends on the planet's distance from its parent star. John Chambers' programme yielded a number of artificial planetary systems, all of which showed at least one habitable, or possibly habitable, planet. ...

... The planets differ greatly in size and properties, and their fields differ too. ... In 1959, after the Earth's radiation belt had been discovered, Frank Drake observed Jupiter and concluded from the relative intensities in a range of wavelengths that the signal was probably emitted by electrons trapped in a strong magnetic field. Then in 1973 the space probe Pioneer 10 passed by Jupiter and found there, sure enough, an enormous planetary magnetic field and a very intense radiation belt. ...

... Physical conditions in the observable atmosphere of the brown dwarf Gl 229B are intermediate between those found in a giant planet atmosphere, such as Jupiter's, and a stellar atmosphere. In one important respect, however, Gl 229B shares kinship with giant planet atmospheres: temperatures in the observable atmosphere are cool enough that the gas is essentially completely molecular. ...

... More on 51 Peg: . The discovery of a Jupiter--mass planet in orbit around the solar--type star 51Peg has been reported by Michel Mayor and Didier Queloz (Geneva Observatory) on October 6th at the 9th Cambridge workshop on "cool stars, stellar systems, and the sun" held at Florence (Italy). ... Recall that the measurements of radial velocity only yield v sin i which in turn gives us M sin i. For most values of i, sin i will be greater than 0.5 and this gives a mass estimate of 0.5 Jupiter masses. ...
