NASA has discovered a new interstellar comet that's currently located about 420 million miles away from Earth.

The new interstellar comet's official name is 3I/ATLAS.

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.

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.
