NASA discovers alien solar system with tighlty packed planets in unsusual orbits

New Delhi: NASA's exoplanet hunter, Kepler telescope found a bizarre alien solar system that has tiny spaced planet with unique orbits. The system, dubbed as Kepler-80 after it's discoverer, is located about 1,000 light years away from the Earth.

Mariah MacDonald with Darin Ragozzine from Florida Institute of Technology carefully studied the rare planetary structure of the solar system. The study reveals that Kepler-80 consists of four exoplanets and a dwarf star that orbit around the same star with years equivalent to one, three, four, seven and nine Earth days.

The size of all the four rocky exoplanets are about 20% to 50% wider than our home planet. Two of the four planets, known as K2-72c and K2-72e, appear to be in the star's "habitable zone" — that just-right range of distances at which liquid water can exist on a world's surface, according to Space.com reports.

One special attribute of Kepler-80 is the outer four planets return to almost exactly the same configuration after every 27 days, according to the scientists. This solar system was first discovered by Kepler in 2012.
