An unidentified piece of space debris originating from beyond the Moon is giving astronomers the rare chance to observe an object on a collision course with Earth.


The object, named WT1190F, is unique in that its trajectory has been unusually easy for scientists to determine; with most space objects, accurately pinpointing a date of impact is difficult. But Bill Gray, from NASA’s Jet Propulsion Laboratory, has even established a time for entry: 6:20 AM UTC, on November 13.

WT1190F’s entry will give astronomers across the globe the chance to test out the network they’ve established amongst themselves in case a more dangerous space object sets its course for Earth.
