The main factor that allows you to compare our planet found their position. Are in stellar ecosphere, and therefore the temperature at which ranges from 0 to 100 ° C. According to the online edition of the British newspaper “Independent”, it gives hope for the existence of water on their surfaces that enable organisms to life.
– There are probably rocky planets, so if there could be water, it would be in a liquid state – Charles Wojcicki admits the Copernicus Science Centre.
Two of the discovered planets – Kepler and Kepler-438b -442b – even orbit around a Sun-like, red star. However, it is smaller and colder.
Scientists have occurred similar findings, although it was always much larger than the planets in our – Kepler-186f is about 110 percent. larger than Earth, and Kepler-62f as much as 140 percent.
This time, one of the discovered planets is only 12 percent. the size of Earth, and the second – just over 30 percent. Importantly, the Kepler-422b receives from its star roughly two-thirds of sunlight that reaches the Earth. In contrast, Kepler-438b receives 40 percent. more light than our planet.
– Unfortunately, at the moment it is not possible for man to personally examine their latest discovery. One of the planets is distant from us 470 light-years, and the second up to 1100. In comparison, the farthest distance from the Earth, which failed to reach Voyager 1 probe, it’s almost 37 hours of light. It took her less than 38 years. The probe has traveled approximately 19 billion 57 million 598 thousand 680 km. Therefore, a trip to Kepler-438b take us about 4 228 476 years – Wojcicki added.
