New interstellar object candidate heading toward the sun angielski

There’s a new object in the solar system headed toward the sun, and it may have come from interstellar space. We only know of two other interstellar objects that have entered into our solar system before, ‘Oumuamua and Comet 2I/Borisov. The nature of ‘Oumuamua is still a matter of debate, and the second was a comet from another solar system. And now we may have a third interstellar visitor. Currently named A11pl3Z, this object has a trajectory that suggests it didn’t originate inside our own solar system.

The International Astronomical Union’s Minor Planet Center added the object to their Near-Earth Object confirmation list on July 1, 2025. The object is also on NASA/JPL’s website for Near-Earth Object Confirmation Page under A11pl3Z. Despite being listed as a near-Earth object, there is no fear of it hitting Earth or even coming particularly close.

The dim space rock is currently at about magnitude 18.8. Our new visitor, A11pl3Z, will get its closest to the sun – at about 2 astronomical units (AU), or twice as far as Earth is from the sun – in October. As it reaches perihelion – its closest point to the sun – it should be moving at about 68 km/s relative to the sun, or at about 152,000 miles per hour.

Marshall Eubanks, a physicist and VLBI radio astronomer and co-founder of Space Initiatives, said on the Minor Planet Mailing List that the object could be as large as 12 miles (20 km) in diameter. It will also come within about 0.4 AU of Mars in October, which would make it just barely observable by the Mars Reconnaissance Orbiter.
