Five new planets have been discovered outside our solar system, all orbiting a sun-like star located within the constellation Aquarius, nearly 620 light years from Earth. The alien worlds are considered super-Earths, sizing in at two to three times larger than our own blue planet.All five exoplanets are likely scorchingly hot: Each planet comes incredibly close to its star, streaking around in just 13 days at most — a whirlwind of an orbit compared with Earth’s 365-day year.
