Interstellar visitor Comet 3I/ATLAS was discovered just a week ago and ever since, astronomers across the world have been ...

You can watch comet 3I/ATLAS live online tonight (July 3), thanks to the Virtual Telescope Project, which will livestream views beginning at 6:00 p.m. EDT (2200 GMT).

A diagram shows the trajectory of interstellar Comet 3I/ATLAS as it passes through the solar system. It will make its closest approach to the sun in October.

I/ATLAS, also known as C/2025 N1 (ATLAS), originated in a distant star system, far beyond the boundaries of our solar system.

But now 3I/ATLAS appears to be a comet like Borisov, the second interstellar object observed. For a comet, the brightness comes from sunlight bouncing off a plume of gas and dust known as a coma ...

Astronomers have confirmed the presence of 3I/ATLAS, a rare interstellar comet originating from a distant star system, now traversing our solar system.

“ [Comet 3I/ATLAS] will be a tiebreaker of sorts,” says Mario Jurić, an astronomer at the University of Washington and discovery software lead at the recently completed Vera C. Rubin ...

Astronomers do know that 3I/ATLAS is a comet that's about 670 million kilometers (416 million miles) away from the sun. Based on current projections, it poses no danger to planet Earth.

NASA has identified 3I/ATLAS as a rare interstellar object, the third ever spotted. Originally named A11pl3Z, this comet is moving at 152,000 mph and will reach its closest point to the Sun on Oct 30.

3I/ATLAS’s status now As per NASA, 3I/ATLAS is 4.5 astronomical units (converting to 670 million kilometres) away from the Sun, with a magnitude of 18.8. However, the comet is expected to get slightly ...

Comet 3I/ATLAS will get as close as 210 million kilometers (130 million miles) from the Sun, far beyond the orbit of Earth, on October 30, 2025.
