NASA finds new interstellar comet passing through solar system
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.
New interstellar comet will keep a safe distance from Earth, NASA says
The space agency spotted the quick-moving object with the Atlas telescope in Chile earlier this week, and confirmed it was a comet from another star system. It’s officially the third known interstellar object to pass through our solar system and poses no threat to Earth.

Comet last seen by Neanderthals 80,000 years ago could be visible again this weekend - MSNIt’s thought the comet was last seen from Earth by Neanderthals more than 80,000 years ago, and stargazers have already spotted it in the southern hemisphere this time around.
A newly discovered comet, called C/2025 F2 (SWAN), may have disintegrated. But the remnants are still visible.
Researchers got an up-close look at the largest comet ever observed, C/2014 UN271, hurtling toward the sun from the Oort Cloud and measuring 85 miles across with jets of carbon monoxide gas.
Observations of comet C/2014 UN271 with ALMA detected complex carbon monoxide outgassing at 16.6 AU, confirming it as the largest Oort Cloud comet known, with a nucleus about 140 km across.
Comet SWAN, hailing from the Oort Cloud beyond Pluto, may not have survived its recent trip past the sun and is fading fast. April 21, 2025, 11:52 AM EDT / Source: The Associated Press.
Indeed, the fictional comet that doomed Earth in the film “Don’t Look Up” came from the Oort Cloud. New Oort Cloud comets are discovered all the time, a dozen or so per year in recent years.
