Back in 2015, Halloween was also celebrated in the skies, as a skull-shaped asteroid flew by earth on Oct. 31.
The asteroid is coming back next year, but it’ll be a little late for the Halloween parties. Halloween asteroid 2015 TB145 will make its return in mid-November 2018, according to a release from the Institute of Astrophysics of Andalusia in Spain. It makes a lap around Earth ever 3.04 years, according to Space.com. It also reflects about five or six percent of the sunlight that hits it, making it just slightly more reflective than charcoal for comparison. Astronomers also think it could be a dead comet.
