Astronomers discover planet with 3 suns located 340 light years from Earth


A team of astronomers led by the University of Arizona discovered a planet HD 131399Ab which is unlikely any other known world – one with, by far, the widest known orbit within a multi-star system. The discovery was published in an early online edition of the journal Science on July 7. This is one of the rare planets and has either constant daylight or triple sunrises and sunsets each day depending on the seasons.

Located about 340 light years from Earth in the constellation Centaurus, HD 131399Ab is believed to be about 16 million years old, making it one of the youngest exoplanets discovered to date. With a temperature of 850 kelvins (about 1,070 F or 580 C) and weighing in at an estimated four Jupiter masses, it is also one of the coldest and least massive directly-imaged exoplanets.
