2025 GN1 is a near-Earth asteroid discovered by the Cerro Tololo-DECam on 4 April 2025. It is noted for its extreme short orbit period around the Sun (113 days).
Orbit
[edit]2025 GN1 has an orbit very similar to 2021 PH27, which has the shortest orbital period around the Sun (also 113 days). This similarity gave rise to a hypothesis, that 2025 GN1 is a pair asteroid of 2021 PH27. The two objects might have formed as fragments of a larger parent after a close encounter with Venus 11,000 years ago. 2025 GN1 is expected to fly close to Venus in 2,300 years, possibly even impacting the planet.[1]
