NASA has discovered an interstellar comet that's wandered into our backyard. Luckily, it won't get near enough to be a threat to our planet.

There are lots of objects floating around in our solar system, but one thing most have in common is a common origin, and then there's 3I/ATLAS.

Officially named 3I/ATLAS, the comet was confirmed as having originated outside of Earth's solar system on July 3, according to the European Space Agency (ESA) and NASA. It is believed to be about 20 kilometers, or over 12 miles wide, according to the ESA and traveling at about 60 kilometers, or 37 miles per second relative to the sun.
