Scientists of Louisiana University concede that Solar System may include one more planet.



This supposed planet, called Tyche may be a gas giant which is 4 times larger than Jupiter is. Its distance to Sun is 15,000 times bigger than the one between Earth and Sun.
Specialists say that the proofs of Tyche existing have already been collected by NASA – Wise telescope and the information is being checked now. If the 9th planet of Solar System really exists it probably consists mostly of helium and hydrogen and the temperature of its surface may be about 73 degrees Celsius.
