Whenever people think about about how many planets exist in the solar system, they think there are eight planets and three dwarf planets. After that, they'll probably say that very few other planets exist in the entire universe. However, that statement was now proven wrong this Wednesday when astronomers said there were billions of planets that had been ejected from different planetary systems. These planets were either floating around in their own lonely ways or attached to stars distant miles miles away from the Solar System. And these aren't just dwarf planets. For every 200 hundred stars in the Milky Way Galaxy, there are two Jupiter-mass planets. This discovery has forced scientists to look more into the realm of exoplanets, which are planets outside our Solar System. Why already, NASA has been planning to conduct an experiment related to this subject with its spacecraft, Wfirst, which may soon be released.
Apparently, this amazing discovery has lead scientists to the possibility that there may be as many planets as stars. If you want to read more about this article, visit http://www.nytimes.com/2011/05/19/science/space/19planets.html?partner=rss&emc=rss.
