A11pl3Z, spotted July 1, 2025, is a candidate interstellar object, likely the third to visit our solar system. It's about 20 km wide, moving at 66 km/s with a hyperbolic orbit (eccentricity ~10.4).

Closest Sun approach is October 2025 at 1.4 AU, Earth at 2.4 AU in December. Its 175° inclination suggests an origin in the Milky Way’s disk.

ESA and astronomers lean toward interstellar status, but the Minor Planet Center’s final confirmation is pending.

No collision risk; it’s a chance to study extrasolar material. Data is preliminary, so some uncertainty remains.
