Third confirmed interstellar object 3I/ATLAS approaches the Sun in October
Astronomers have discovered 3I/ATLAS, the third known interstellar object passing through our Solar System, notable for its high speed and comet-like features. It will make its closest approach to the Sun in October, providing months of observation opportunities before it leaves the Solar System next year.
Why it matters: 3I/ATLAS is the fastest interstellar visitor detected, offering a rare chance to study material from beyond our Solar System.
The big picture: With new telescopes like the Vera C. Rubin Observatory, astronomers expect to find several interstellar objects annually, expanding our knowledge of the cosmos.
Stunning stat: 3I/ATLAS is traveling at about 60 km/s, significantly faster than previous interstellar objects 'Oumuamua and 2I/Borisov.
Commenters say: Many highlight the improved detection capabilities enabling these discoveries and discuss the object's unusual speed, size estimates, and the potential for more interstellar visitors soon.
