The astronomy world is abuzz with the discovery of a new visitor to the solar system, not an asteroid or comet but an object from interstellar space, similar to สปOumuamua in 2017.

Its hyberbolic orbit with eccentricity 6 implies it came from and is headed to far beyond the solar system.

The object officially named 3I/ATLAS and C/2025 N1 (aka A11pl3Z) will not pass close to Earth; perihelion will be around Oct 29, just inside the orbit of Mars.

Size: 20 km?
