Near-Earth asteroid of the Atira group
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).
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.[2]
