New, Distant Planets Discovered
RENEE MONTAGNE, host:
And in more space news, astronomers have announced the discovery of 28 more planets outside our solar system. This discovery brings the total number of planets in different solar systems to 236. Some of the new guys are part of multiple planet systems which orbit around a central star much like our own solar system. All of the new planets are gas giants like Jupiter, with no solid surface. But smaller Earth-like planets could be in the same system, astronomers say. They're just too small to detect.
