NASA's orbiting Kepler telescope has spotted a rocky exoplanet, called Kepler-10b, which is around 560 light years away from our solar system and 1.5 times wider than Earth.
The Kepler spacecraft, which was launched in March 2009, has been assigned to find exoplanets where life might exist. It has more than 150,000 stars in its range.
Exoplanets spotted so far are gaseous. But, Kepler-10b is made up of rocks, and thus it solid and not gaseous. One can stand on it.
Douglas Hudgins, Kelper programme scientist at NASA, described the discovery as "significant milestone".
Speaking on the topic, he said, "The discovery of Kepler-10b is a significant milestone in the search for planets similar to our own."
But, the Kepler-10b is not suitable for supporting life as temperatures soar up to 2,500 degree Fahrenheit and there is no water on it. It is surrounded by clouds of toxic melted silicon.
Kepler-10b orbits its star in merely 84 days. Its distance from its star is 20 times lesser than that of Mercury's from the Sun. It is around 4.6 times heavier than Earth.
Scientists want to confirm if we are alone in our galaxy.
