Many extrasolar planets have been found and diverse character. Some of them have peculiarities, such as orbiting two suns. Astronomers had studied the planet 55 Cancri e. The planet is orbiting a star 40 light years away from Earth, and was discovered in 2004. This is the most bizarre planet.

Research over the past few years revealed that 55 Cancri e entered the category of super-earth, mass 99 times Earth's. Observations of this planet do when planets transit in front of the star. Known, 55 Cancri e stopover in advance its star every 18 hours. So far, astronomers suspect that the condition of 55 Cancri e is very hot and cruel. This is because the distance of the planet and the star is very close, 26 times closer distance of the Sun-Mercury.

However, recent research reveals that 55 Cancri e is not as assumed. Despite the close distance of the planet and its star, the planet has a liquid, including water. Liquid on the planet was not as envisaged, instead of the ocean as on Earth. The liquid contained inside, and seeps out through the rocks.

The existence of this fluid is strange because the planet's surface temperature reaches 1,000 degrees Celsius. According to astronomers, the condition is possible because each fluid is in the super-critical conditions, the temperature is more than the boiling point (100 degrees for water), but remain in liquid form. As a result of water seepage into the surface of the planet, the planet's atmosphere becomes very hot and steamy. And, it can be detected from a distance of 40 light years.

The research was carried out by Brice-Olivier Demory from the Massachusets Institute of Technology and published in Astronomy and Astrophysics.
