US EditionESA Confirms A11pl3Z as Third Known Interstellar Visitor
- Earlier this week, the ATLAS survey team detected A11pl3Z on July 1, designating it as a potential third interstellar visitor.
- Following the detection, astronomers traced A11pl3Z's path back to June 14, estimating eccentricity at six, confirming its interstellar origin, as explained by Paul Weigert.
- Analysis shows A11pl3Z is moving faster than previous interstellar objects, with an estimated diameter of 10–20 kilometers, confirmed by astronomers including Weigert.
- The interstellar object A11pl3Z will pass near Mars in October, with perihelion expected then, and will remain observable through next year, offering rare scientific study opportunities.
- Beyond this encounter, the Vera C. Rubin Observatory could detect interstellar visitors monthly, offering rare opportunities to study extrasolar material and improve future detection rates.

After Oumuamua and Borisov a third interstellar visitor reaches our solar system. The comet still holds many secrets.
Third interstellar object detected racing through solar system
Astronomers on Wednesday confirmed the discovery of an interstellar object racing through our solar system — only the third ever spotted, though scientists suspect many more may slip past unnoticed. The visitor from the stars, designated 3I/Atlas, is likely the largest yet detected and has been classified as a comet, or cosmic snowball. “It looks kind of fuzzy,” said Peter Veres, an astronomer with the International Astronomical Union’s Minor Pl…
Telescopes of the Teide and La Palma Observatory are part of the world's "giantesque battery" that for 48 hours has observed an object of between 20 and 30 kilometers that seems to come from outside the solar system, reports astronomer Javier Licandro.The object, provisionally called A11pl3Z, was observed two nights ago for the first time from one of the ATLAS telescopes in Chile, an early warning network for the discovery of asteroids that pass…
The interstellar celestial body is coming from the direction of the constellation Sagittarius, and is currently 670 million kilometers away from the Sun.
