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.

NASA has discovered the interstellar comet 3I/Atlas, located 4.5 au from the Sun, offering a rare glimpse into celestial bodies from outside our solar system. Scientists confirm it poses no threat to Earth as it passes closely by in late October.

NASA has discovered a new interstellar comet that's currently located about 420 million miles away from Earth. The space agency spotted the quick-moving object with the Atlas telescope in Chile on Tuesday and confirmed it was a comet from another star system. The new interstellar comet's official name is 3I/ATLAS.
