Wikipedia Overview
2021 PH27 is a kilometer-sized Atira-type near-Earth asteroid orbiting very close to the Sun. It was discovered by Scott Sheppard using the Dark Energy Camera (DECam) at Cerro Tololo Inter-American Observatory on 13 August 2021. 2021 PH27 has the smallest semi-major axis and shortest orbital period among all known asteroids as of 2026, with a velocity at perihelion of 106 km/s (240,000 mph). It also has the largest relativistic perihelion shift of any known object orbiting the Sun, 1.6 times that of Mercury. 2021 PH27 shares an identical orbit and color as 2025 GN1, which has led astronomers to believe that the two asteroids split apart from a parent body over 10,500 years ago.
