More than 10 percent of all extrasolar planets have oceans




More than 10 percent of all extrasolar planets have on their surface oceans. These are the results of computer calculations performed by the Japanese researcher from the Tokyo University of Technology. 44-year-old Shigeru Ida published them on the eve of a major scientific symposium, which will open on May 9 in the capital of the neighboring city of Chiba.

Conclusions The Japanese can not be tested in practice: the source of life is possible only on the so-called solid planets, which include our Earth, but because of the small size, they are not available even for the most powerful modern telescopes.

Since 1995, outside the solar system discovered about 120 new planets, but they all relate to the type of gas giants like Jupiter, which has a hard shell and is composed mainly of hydrogen and helium.

However, with the supercomputer could calculate the proportions in which to each other are gas and solid world. Calculations show that in the space of roughly equal.

With more than ten percent of rocky planets distant from their stars about the same distance as Earth is from the Sun. The mass of these planets range from 0.1 to 10 Earth masses, and the temperature and atmospheric conditions make possible the existence of oceans of water for billions of years.
