A piece of unidentified space junk is heading straight for Earth and scientists have no idea what it is.

The space object is projected to fall to earth on November 7. It is 7 feet long and scientists think, but don't know for sure, that the object is part of a rocket body. Earthfall is expected to be in the Indian Ocean 40 miles from the island of Sri Lanka.

According to the European Space Agency,

The expected 13 November reentry of what is likely to be a rocket body poses very little risk to anyone but could help scientists improve our understanding of how any object – man-made or natural – interacts with Earth’s atmosphere.

As confirmed by experts at ESA's NEO Coordination Centre (NEOCC), ESRIN, Italy, the object, dubbed WT1190F, is thought to be a discarded rocket body; it is orbiting Earth every three weeks in a highly ‘eccentric’ – that is, non-circular – orbit.

There are thousands of pieces of space debris and some that are unexplained like the legendary Black Knight Satellite which was first observed orbiting Earth long before mankind achieved the technology to launch objects into space.
