A11pl3Z should make its closest approach to the Sun on October 29 and its closest approach to Earth on October 30, both at a distance of 1.35 au.

A11pl3Z was first noticed by NASA’s Asteroid Terrestrial-impact Last Alert System (ATLAS). Earlier images of the object caught by ATLAS, but not spotted at the time, have since been found in ...

Is the solar system an interstellar highway, with cosmic objects speeding past at warp speeds without human notice? That’s ...

A purely circular orbit has an eccentricity value of 0, and anything above 1 is hyperbolic. Essentially, this is a very, very strong indication that A11pl3Z originated outside of the Solar System.

A newly discovered object, dubbed A11pl3Z, appears to be moving too fast and straight to have originated in the solar system. If confirmed, it will be the third interstellar visitor ever spotted.

If A11pl3Z is a space rock, it's surprisingly massive compared to the other two interstellar objects that have passed by Earth. However, scientists don't project that the mystery object will get ...

This obfuscates exactly how fast A11pl3Z is traveling, and in what direction. While it's still possible that A11pl3Z is just a very odd object from our solar system, it looks very interstellar.

It’s too soon to know whether the object, designated for now as A11pl3Z, is a rocky asteroid or a icy comet, or how big and what shape it is. More observations are needed to confirm its origins.

On Wednesday (July 2), NASA released a statement confirming that A11pl3Z is indeed an interstellar object and will not remain in the solar system for long. The researchers also shared the object's ...

A11pl3Z could prove different. First, it's still inbound, currently just inside the orbit of Jupiter. The object reaches perihelion in a few months on October 29th, 2025 at about 1.35 astronomical ...

– A11pl3Z causes excitement So far, two interstellar celestial bodies have been discovered hurtling through the solar system. Evidence of the next one is now mounting.

Scientists at ESA have spotted A11pl3Z, a possible interstellar object near Jupiter. Though it’s heading towards Earth, experts say it poses no threat and will pass Mars instead.
