3I/ATLAS is 7 miles wide — the largest interstellar object ever seen — new photos from Vera C. Rubin Observatory reveal
The extraterrestrial comet 3i / Atlas measures approximately 7 miles (11.2 kilometers) wide, which makes it the largest interstellar object ever identified, according to the newly revealed photos of the VERA C. Rubin Observatory.
The detailed images, which have been captured before the official discovery of the extrasolar entity, highlight the immense power of the record telescope and demonstrate how precious it will be to find future interstellar workers, according to the researchers.
3i / Atlas was Discovered on July 1Going towards the sun at more than 130,000 MPH (210,000 km / h). Less than 24 hours later, NASA had confirmed that It was the third known interstellar object (ISO) – A piece ejected from an extraterrestrial star system that pulls clean through our solar system. It’s quickly has become clear that 3i / Atlas was a cometand computer simulations withdrawing its probable region of origin indicates that it could have up to 3 billion years more than the land, potentially Which makes it the oldest comet ever detected.
So far, everything The researchers were able to discover About the size of the comet was that her coma – the ice, dust and gas cloud that surrounds her – was up to 15 miles (24 km) in diameter. However, the size of its frozen nucleus, or outer shell, has remained a mystery.
But in a new study, downloaded on July 17 on the preparation server arxivA group of more than 200 researchers was able to find images of the comet in the vast set of early data by Vera C. Rubin, revealing the probable size of the nucleus.
The images, which were taken on June 21, suggest that the comet’s nucleus has a probable radius of approximately 3.5 miles – or a diameter of about 7 miles – with an error equal to approximately 0.4 mile (0.7 km).

Until now, only two other ISOs have never been confirmed: 1i / ‘Oumuamua, a asteroid discovered in 2017; and 2i / Borisov, a comet spotted in 2019. Astronomers have long suspected that many more ISO Passed through the unlawful solar system.
‘Oumaumua is supposed to be About 0.2 mile (0.4 km) wideAlthough its exact shape was not clear, while the comet Borisov has a nucleus about 0.6 mile (1 km) wide. This means that 3i / Atlas is comfortably the largest ISO never seen.
The new study also gave scientists a good overview of the comet of the comet and helped to identify large amounts of dust and water ice surrounding its nucleus. These additional results are additional evidence that 3i / Atlas is a natural comet – not a disguised survey sent here by an advanced extraterrestrial civilization, as some researchers have Controversial proposed in recent weeks.
The Vera C. Rubin observatory, located in the Chilean Andes, is equipped with The largest digital camera in the worldWho is about to start a 10 -year mission to scan the sky of the southern hemisphere, known as Legacy Survey of Space and Time (LSST). The telescope published his first images in Junerevealing more than 10 million galaxies in unprecedented detailsand has already discovered thousands of new asteroids.
The fact that the newly published photos can determine the size of 3i / Atlas, 10 days before the discovery of the object, is proof of what Vera C. Rubin will be able to accomplish when it is entirely activated later this year, wrote the study team.
Many experts believe that the observatory will revolutionize the study of ISO and predict that it could identify up to 50 new extraterrestrial intruders during the next decade, according to Forbes.
