Apparently an asteroid came closer to Earth than any other asteroid in NASA’s database on Halloween night.

The asteroid — known as COPPEV1 or 2019 UN13 — flew close to Earth early Thursday morning. The Cataline Sky Survey and the Mt. Lemmon Steward Observatory (both in Arizona) and the Magdalena Ridge Observatory (in New Mexico) spotted the asteroid as it came close to Earth, according to CNET.

And, based on the data from those observatories, “the asteroid came closer to the surface of our planet (without actually colliding with our atmosphere) than any other close approach in NASA’s database of known near-Earth objects.”

Simulations showed the asteroid flew over southern Africa came within 3,852 miles at the beginning of its closest moment.

“To get an idea of how close this is, consider that many telecommunications satellites orbit at an altitude of 22,236 miles,” according to CNET.

According to EarthSky, small asteroids can come close to Earth pretty often. The Nuclear Test Ban Treaty Organization said in 2014 that it noticed 24 atom-bomb-scale asteroid impacts to Earth since the year 2000, an indication that surprise asteroids like this aren’t a rarity.

“What’s really remarkable about this spooky space rock sighting is that it speaks to how astronomers are getting better at spotting incoming asteroids,” according to CNET. “It’s very possible that we’re getting buzzed by cosmic boulders on the regs, and always have been, but we’re just now getting a sense of how much traffic is really up there.”
