(875163) is an Apollo-type near-Earth asteroid with an estimated diameter of about . It was discovered by the Spacewatch survey of the Kitt Peak National Observatory from Arizona, USA on 17 September 1998.

Physical characteristics Infrared observations from the NEOWISE spacecraft revealed that asteroid may have a diameter of about assuming a geometric albedo of about 0.058. Astrometric measurements up to 2025 revealed orbital perturbations consistent with weak outgassing, indicating that this object might be also a comet.

Orbit , currently has a perihelion of about and aphelion of about from the Sun, completing one revolution once every 4.54 years.

It made a close encounter with Earth at a distance of on 30 August 2025. By 2037, it will approach Jupiter at a distance of , followed by another Earth flyby at away on 8 September 2052. It is considered a potentially hazardous asteroid, however there is no significant impact risk with Earth in the foreseeable future.
