1020003

1020003 was first identified on 1 March 2021 by the Pan‑STARRS survey at Haleakala. It is a main‑belt asteroid orbiting the Sun between 2.4 and 3.1 astronomical units. Its orbital elements (epoch 2025‑01‑01) are: semi‑major axis 2.78 AU, eccentricity 0.06, inclination 8.2°. The taxonomy based on visible‑spectrum measurements classifies it as an S‑type asteroid. The estimated albedo of 0.22 and absolute magnitude 12.6 suggest a diameter of roughly 8 km.

Lightcurves collected in 2023 indicate a rotation period of 5.2 hours with amplitude 0.07 mag, consistent with a nearly spherical shape. No maser or binary companion has been detected. 1020003 has not yet been given a formal name; it remains in the Minor Planet Center numbering system awaiting official designation. The asteroid is listed in several astronomical databases such as the JPL Small‑Body Database and the Minor Planet Center. The object provides a typical example of compositionally modest, medium‑sized bodies in the inner asteroid belt. Its observation arc extends over 2.5 years, enabling accurate ephemerides for future spacecraft flybys or ground‑based studies.
