The Three TerrasPosted: July 23, 2008
A trio of ‘super-Earths’ has been found, amongst a batch of 45 new, extra-solar planets.
Last month astronomers reported to a conference in that they had found three large, rocky planets orbiting a single star 42 light years from Earth. This brings the total of planets found outside our solar system, since the first one in 1995, to 270.
These planets were discovered by careful observations of tiny wobbles in the star they orbit caused by the gravitational drag they exert.
