is a small near-Earth asteroid and the most recently discovered quasi-satellite of Earth. First observed on 2 August 2025 by the Pan-STARRS 1 telescope at Haleakala Observatory in Hawaii, is a member of the Arjuna asteroid groupâÂÂnear-Earth objects with orbits very similar to Earth's.
was discovered on 2 August 2025 by the Pan-STARRS 1 telescope at HaleakalÃÂ Observatory in Hawaii, United States. The asteroid was formally announced by the Minor Planet Center (MPC) in a Minor Planet Electronic Circular on 29 August.
Upon discovery, the asteroid was first given the temporary internal designation P12dHmP. Once it was formally announced on 29 August, it was assigned the provisional designation ' by the MPC.
is an Apollo asteroid with a semi-major axis of 1.003 AU, an orbital eccentricity of 0.108, and an orbital inclination of approximately 2ð, placing it in the low-eccentricity, low-inclination Arjuna class. Unlike Earth's natural satellite, the Moon, is not gravitationally bound to Earth. It maintains a 1:1 mean-motion resonance with Earth, making it a quasi-satellite. From Earth's perspective, the asteroid appears to hover nearby.
joins a small group of known quasi-satellites of Earth, including 164207 Cardea, 469219 KamoâÂÂoalewa, , , , and . Quasi-satellites like are temporarily co-orbital with Earth but are not true moons. Some Arjuna-class asteroids with particularly Earth-like orbits can occasionally become temporary mini-moons, gravitationally captured by Earth for months to years.
During its closest approach, comes within approximately 299,000 km of Earth, while at its farthest it can be tens of millions of kilometers away. Over time, it may transition between quasi-satellite and horseshoe orbits due to gravitational perturbations.
