US EditionInterstellar Comet 3I/Atlas Enters Inner Solar System
- On July 1, the ATLAS Survey in Chile detected the third known interstellar object, designated 3I/ATLAS, marking a rare astronomical milestone.
- ESA's trajectory analysis indicates 3I/ATLAS is traveling over 60 km/s on a hyperbolic path, confirming its interstellar origin, and will not threaten Earth.
- Measurements indicate the interstellar object is about 10 km in diameter, traveling at 60 km/s with a faint coma, roughly 420 million miles from Earth.
- NASA confirms the interstellar object will stay over 150 million miles from Earth, passing inside Mars’ orbit later this year with visibility through December.
- Scientists anticipate the Vera C. Rubin Observatory will significantly increase detection of interstellar objects, offering insights into their composition and origins, as many more likely pass through annually.

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.
An interstellar comet is making a temporary visit to our solar system, something that has only been observed twice before. However, there is no risk that the comet will collide with Earth.
