Detecting tiny planet was the first evidence for the theory that the planets orbiting stars in our galaxy may have a much smaller size than the planets in our solar system.

The existence of the planet Kepler 37-b, nearest to the star Kepler-37 from three planets have been confirmed in the journal Nature.

"The fact that we found one of these little ones, and therefore difficult to detect planets indicates their high prevalence around other stars, and confirms the theory that at least reduce the size of the planets, their number increases exponentially," - said Dr. Dennis Stella from Australia.

Kepler-37b - is an extrasolar planet (planet located outside our solar system), which, according to scientists, is similar in size to the Moon, the diameter of which is only 3475.

This extremely small size causes very much exposed surface. Earth-like planet Kepler-37b, like Mercury has no atmosphere or water.

Found this planet by the Kepler telescope, which was launched in 2009.

Astroseismology analysis showed that treatment radius Kepler-37 by approximately 20 percent less than the size of the sun.
