On which planets can there be living creatures?

B. The astronomers are studying the planets outside our solar system to find out if there is any living thing on any planet. Many planets are millions of light years away from Earth. Such planets are not even visible through a telescope. Astronomers estimate the color and movement of its star. It is unknown at this time what he will do after leaving the post.

No planet should be so close to its own sun that it is too hot or too cold to be too cold. There should be water on the planet. The cells of living things contain 90% water. Without water, vital juices do not form. The body structure of an organism is mainly based on carbon, so there must be chemicals containing carbon on the planet, and finally the earth needs land for living things to grow, but the planets are just spheres of air and clouds. It is likely to have life on a planet with solid land or a rocky surface. To date, scientists have found thousands of planets outside the solar system that meet some of these conditions, called extrasolar planets.
