There is a small solar system!

Astronomers have discovered what they believe is about to be the birth of the smallest solar system: from astronomical observations from the ground as well as from space telescopes, they have discovered a halo. brown, less than 1% solar mass, surrounded by a disk of dust and gas.

Kevin Luhman of Pennsylvania State University, who led a group of scientists who announced the discovery, said the small brown halo, identified by the 500-light-year constellation Chamaeleon, is in the process of forming an act. fine, and maybe one day to form a solar system.

For a long time, many people believed that our solar system formed when a giant cloud of dust and gas collapsed to form the sun and planets about 4.5 billion years ago. This new discovery is noted with the properties of planet formation. If this disk of dust forms a planet, there will be a new solar system formed about 100 times smaller than our Solar System.

This brown halo is larger than a planet but smaller than a star, thought to have broken gas masses that have gathered enough to form a bright star. It was noted by NASA's Spitzer and Hubble space telescopes as well as from ground observations.
