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.

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.

– 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.

Experts have confirmed that the mysterious object hurtling towards us, previously dubbed A11pl3Z, is an "interstellar object." The cosmic interloper, officially named 3I/ATLAS, is only the third ...

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.

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.

Scientists expect A11pl3Z to approach Mars next October, at a distance of 55 million km, before passing close to Earth in December at a safe distance of about 360 million km.
