Discover the cosmos! ... 2002 June 14 . 55 Cancri: Familiar Planet Discovered . ... The discovery of a Jupiter -like planet in a Jupiter-like orbit around nearby Sun -like star 55 Cancri , announced yesterday, gives a new indication that planetary systems similar to our Solar System likely exist elsewhere. The planet, discovered by G. Marcy ( UC Berkeley ) and collaborators, is one of two new planets found around 55 Cancri -- in 1997 a Jupiter-massed planet was found orbiting very close in. ...

... The 50 so-called exo-planets were discovered using a telescope that is found in South America. ... By looking at a star s wobble, astronomers can work out how many exo-planets are in orbit around it and how heavy they are. After studying all of the planets discovered with this telescope so far, astronomers have found that nearly half of stars that are similar to the Sun have at least one planet that is lighter than Saturn. ... But there are many, many more waiting to be found! ...

My research efforts have focused on three areas which are: . More than 200 extrasolar planets have been discovered around relatively nearby stars, primarily through the Doppler line shifts owing to the reflex motions of their host stars, and more recently through transits of some planets across the face of the host stars. ... Gravitational microlensing provides a novel technique to look for planets around lens stars, and this is the only technique currently capable of detecting Earth-mass planets. ...

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. ...
