Astronomers Find 6-Pack of Planets in Alien Solar System | LiveScience
Astronomers have discovered an alien solar system in which six planets are orbiting a sunlike star, with five of the newfound worlds in close-knit configuration.
Few stars have been observed with planetary arrangements like our solar system, making this a compelling find. The newfound exoplanet system was sighted by astronomers using NASA’s planet-hunting Kepler space observatory.
The smallest of the new alien planets is about 2.3 times the mass of Earth. None of the extrasolar planets are inside the so-called “habitable zone”—– orbits where liquid water could exist on their surfaces, scientists said.
