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.

Astronomers are meticulously tracking the new interstellar visitor that is crossing our solar system. Officially designated as 3I/ATLAS, this object is a comet that originated outside our solar system will soon make its closest approach to the Sun.

The object — thought to be a comet — is only the third-ever confirmed interstellar visitor to pass through our cosmic neighborhood. Dubbed 3I/ATLAS, the comet poses no danger to Earth and will remain roughly 150 million miles away as it speeds by, according to NASA.
