Scientists have deflected inquiries about the discovery of new planet for a few years now, mainly because they feared being associated with these “fringe” theories. But, according to a team of Spanish astronomers who call themselves StarViewer Team they found a brown dwarf star with large satellites encircling it. It’s twice the size of Jupiter
The group made the rounds of all the news web sites in the past two weeks, claiming they discovered something very significant. It’s almost twice the size of Jupiter and just beyond our furthest planetoid, Pluto. Although it’s not a planet, it appears to have planets or large satellites encircling it. It’s what astronomers call a “brown dwarf star” and its official name is “G1.9″.
What’s a Brown Dwarf Star?
All matter attracts other matter. A larger mass will attract smaller masses towards it. In space this results in growing clouds of matter that tend to clump together and attract more matter. Since most of the matter in space is gaseous, these clouds eventually get so dense that they collapse into dense gaseous spheres. When they do this there is usually some “left over” matter that forms a ring around the sphere.
If there is enough matter in a sphere of hydrogen, for example, it can cause so much compression at the shpere’s core that the hydrogen atoms begin to fuse together and a fusion-reaction ignites a new born star. In this reaction two hydrogen atoms join together to form one helium atom and release extra energy as radiation. Scientists believe that the minimum mass needed to ignite a sun is about 13 times the known mass of the planet Jupiter — written as “13MJ.” If the mass is lower than this, the pressure in the core is not enough to ignite and the sphere will be hot ball of gas called a “brown dwarf.”
