Based on the number and variety of planets found around these stars , the team estimates that about 40 percent of all sunlike stars in the galaxy host at least one planet that is less massive than the gas giant saturn .
Another kepler data release is scheduled for february and once again there will probably be a flurry of blogs speculating if the mission has found the interstellar holy grail -- an earth-sized planet in the balmy habitable zone about a sunlike star .
The bigger star exploded , leaving behind a neutron star . Meanwhile , the sunlike star aged in the normal way , eventually swelling , blowing off its outer layers and collapsing to the white hot ember known as a white dwarf star .
Using their own independent software for analyzing kepler 's potential planet detections , fressin and his colleagues estimate that about 17 percent , or one in six , of all the sunlike stars in the milky way host a rocky planet that orbits closer than the distance at which mercury orbits our own sun .
At that distance , a sunlike star is visible through binoculars .
在此距离之内,一个像太阳这样的恒星可以通过大型望远镜观测到。
19 On september 30 , 2006 , the french center for national space studies beamedcosmic connexion , a tv program aimed at extraterrestrials , at a sunlike star called errai 45 light-years from earth .
That would include at least some sunlike stars that aren 't part of clusters and that thus offer no other clues to their age , and that , in turn , would tell you the approximate age of any planet that orbits those stars .
When sunlike stars run out of hydrogen fuel , they enter a red giant phase , in which their gas envelopes can swell to several hundred times their original size .
