Wesley Traub, using the analysis of data from the Space Telescope "Kepler" has concluded, that about a third similar to our Sun stars can have Earth-like planets. In the study of 153 thousand stars, the planets have been discovered only a small proportion of them, but it were a planets, comparable in size to Jupiter, since the discovery of planets was based on fluctuations in the brightness of these stars. However, small deviations in the regular changes in brightness of about 34% of the stars in the same class as our Sun, has forced scientist suggested, that these small deviations associated with the existence of small terrestrial planets. However, more accurate data can be done only after analyzing more data, at least 1,000 days of observation.
