// the signal · what the data says
Only three interstellar objects have ever been confirmed. 3I/ATLAS, discovered 2025, passed perihelion on 29 Oct 2025 at 1.36 AU with an excess velocity of ~58 km/s and may be older than the Solar System (~7 Gyr). Near-Earth asteroids like Apophis (2029 close pass) are tracked live by NASA CNEOS.
