"Nomad planets" could be surprisingly common in our bustling galaxy, according to researchers at the Kavli Institute for Particle Astrophysics and Cosmology (KIPAC), a joint institute of Stanford University and the SLAC National Accelerator Laboratory. The study predicts that there may be 100,000 times more of these wandering, homeless planets than stars in the Milky Way.
Rogue planets - New observations of tiny dark clouds called globulettes suggest that free-floaters may be capable of arising within. A team of astronomers from Sweden and Finland recently observed globulettes in the Rosette Nebula, a massive cloud of dust and gas. This nebula is home to about 100 of these tiny clouds. Globulettes are incredibly dense — slightly less than 13 times Jupiter’s mass. So these are tiny blotches of dust and gas that are downright planetary.
