9. The Rock Showers of Planet
The CoRoT-7b is a strange and mysterious planet outside the solar system, and the first rocky planet discovered orbiting a star other than the Sun. It is believed to have been a giant gas planet initially, like Neptune or Saturn, but due to its proximity to its host, it gradually lost its gas and atmosphere layers. Since it is tidally locked, it always faces its star on one side where temperature is can be 4000°F, while the temperature on the side facing away is as about 350°F. The conditions lead to rock rain: vaporized rocks that fall as liquid rock rain, and solidify on the surface of the planet.

8. Planet Methuselah
PSR 1620-26 b is probably the oldest planet of the universe, old enough to defy the traditional astrophysical models. It is triple the age of Earth, and is thought to be just a billion years younger than the universe itself, when traditionally, it is believed that planets cannot be as old as the universe, because, 13.8 billion years ago, at the time of the big bang, the materials required for a planet to form were not there in the universe, then. Methuselah orbits a binary star comprising a white dwarf star and a pulsar, amongst the globular cluster of stars in the Scorpius constellation. Also See: Top 10 upcoming mind blowing technologies
