Everybody expects that there must be planets somewhere since space is so wide. I think so too. We are having trouble finding ones, but some are known as earth-like planets. One of them is a planet called "Gliese-12b" which is 40 light-year away from the earth. The size almost the same as Venus's and is a little smaller than the earth's. The planet goes round the Gliese-12 in 12.8 days. It means one year has only 12.8 days for Gliese-12b. The radiation intensity is as 1.6 times as one of the earth received by the sun. However, the surface temperature is expected to be about 42 degrees and is classified into low temperature in the planets that have ever been discovered. The earth's surface temperature is 15 degrees, so it is a bit hotter. On top of that, it is said that the planet has air, too. On the other hand, Venus's is 460 degrees due to thick CO2 and is so hot planet. That's why it is hard for people to move to and live in. If people can move to "Gliese-12b" and live there in the future, the day might come when we can see the earth from the planet as if it is science fiction movies.
