Asteroid 2017 XA1 — Full Scientific Profile

Asteroid 2017 XA1 is a small near-Earth body with a distinctly interior orbit relative to Earth's — meaning its path around the Sun remains mostly within Earth’s orbital distance. Although it is formally classified as a Potentially Hazardous Asteroid (PHA), its orbit, as determined from three years of observations keeps it at safe distances during close approaches for the foreseeable future.

Abstract

Floating through the inner Solar System with the grace of an orbital dancer, asteroid 2340 Hathor is a fascinating space rock that has captured astronomers’ attention since the mid-1970s. Named after an ancient goddess yet rooted in modern science, Hathor embodies the intersection of myth, celestial mechanics, and planetary defense.

While it poses no imminent danger, Hathor is notable for an upcoming close approach to Earth on 17 January 2026, an event that has placed it firmly back on astronomers’ observation schedules.
