Planetary system similar to solar system discovered

Authors


Abstract

An extra-solar planetary system that has some similarity to our own Solar System has been detected for the first time, a prominent team of planet hunters announced at a briefing on 13 June in Washington, D.C.

A planet orbiting the star 55 Cancri in the constellation Cancer, 41 light years from Earth, is similar to Jupiter in some key aspects, according to the team of astronomers. The planet orbits its star at a distance of about 5.9 astronomical units (AU); this is close to Jupiter's distance of 5.2 AU from the Sun. Also, the new planet's slightly eccentric orbit takes 13 years for one orbit, while Jupiter requires 11.86 years.
