... See also: . ... This video was created by Scott Manley. ... This video highlights 2 groups of asteroids that have orbits in resonance with Jupiter. To highlight the motion we rotate the view at the same speed as an idealized version of Jupiter, that is, we keep the rotation constant as if the planet was on a circular orbit. ... Asteroids which are in this resonance have their orbital eccentricities increase quickly until their orbits cross those of other planets and they suffer a close encounter. ...

... 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. ...

... 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. ...
