US EditionInterstellar Comet 3I/Atlas Enters Inner Solar System
- On July 1, NASA's ATLAS survey in Chile detected the third interstellar object, designated 3I/ATLAS, marking only the third such visitor observed outside our solar system.
- Tracing its hyperbolic trajectory, ESA analysis confirms 3I/ATLAS is traveling over 60 km/s from interstellar space, indicating it is not bound to the Sun.
- NASA and ESA confirm the interstellar object is about 10 km in diameter, traveling at 60 km/s, and roughly 420 million miles from Earth, with a faint coma observed.
- The interstellar object will pass no closer than 150 million miles to Earth, with closest approach near Mars in late October, remaining observable through December.
- Scientists see the discovery of 3I/ATLAS as a breakthrough, with future observatories like Vera C. Rubin expected to find more interstellar objects annually, expanding our understanding of the galaxy.

By Ashley Strickland, CNN A newly discovered object zipping through our solar system is generating excitement among astronomers because it's not from here. Believed to be a comet, it's only the third celestial body from outside our solar system observed in our region of the universe. This interstellar visitor, now officially named 3I/ATLAS, was spotted when the NASA-funded Asteroid Terrestrial-impact Last Alert System (ATLAS) telescope in Chile …

Astronomers spot 3rd object that is not from our solar system
Astronomers are excited after spotting an object speeding at 133,200 miles per hour (about 214,364 kilometres per hour), which is too fast to be from our solar system, CNN reported on Friday. The interstellar object is believed to be a comet, which astronomers from the European Space Agency have officially named 31/ATLAS (Asteroid Terrestrial-Impact Last Alert System), and is the third celestial… Source
A rare guest is just racing through the solar system: 3I/Atlas is completely alien to us. Perhaps the object now reveals more about places in space that we will never see ourselves.
