Astronomers Find a Planet Orbiting a Star Nearly Identical to Our Sun

It took six years to do it , but astronomers have chance upon at least three planet circling adept in a crowded virtuoso cluster some 2,500 light year away from Earth . Even well : One of the planetsis circle a solar twin , a asterisk that ’s nigh identical to our Lord’s Day .

The star cluster in head is known as Messier 67 . Spotted by European Souther Observatory ’s HARPS satellite - hunting telescope in Chile , the exoplanets found there are exceedingly rarefied . ( So farvery few planetshave been discovered in star bunch . ) Two of the three planet have rough a third the deal of Jupiter and orbit their star in about a week . The third is more massive than Jupiter and claim 122 days to revolve . However , the one satellite orbiting the adept very to our sun is without common law .

Given the its composition and location , it ’s virtually inconceivable that the planet orbiting the solar twin could host life . The discovery does show that “ major planet in open wiz bunch are about as common as they are around isolated lead , ” says one of the co - authors of a theme on the unexampled discovery . But in earnest can we just discover aliensalready ? The suspense is killing me . [ ESO ]
