Call them the orphan planets, isolated orbs or lone planets, scientists estimate that there are so many of these undetected moving around in space that they may be double in number than the number of stars.
Planets of the size of Jupiter, as astronomers from a Japan-New Zealand based survey note, have been roaming around without any parent star to revolve around. They first observed about 10s of them when they were looking towards the centre of the milky way galaxy. These new planets they found are about 10,000 to 20,000 light years away from earth, and there are probably many more around.
