2022 UX1

2022 UX1 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.006 AU it takes 1.01 yr to circle the Sun.

Orbit and dynamics

The path is an ellipse reaching 0.745 AU from the Sun at perihelion and 1.267 AU at aphelion, a radial span of 0.522 AU.

Applying Kepler's third law to a = 1.006 AU gives an orbital period of 1.01 yr, or about 369 days.

An eccentricity of 0.259 makes the orbit moderately elongated.

Its inclination of 2.02° keeps it close to the plane of the ecliptic.

By the vis-viva equation its orbital speed rises to 38.7 km/s at perihelion and falls to 22.8 km/s at aphelion.

Because q < 1 AU and Q > 1 AU, this orbit geometrically intersects the region of Earth's orbit.

Size and surface

No direct size measurement is available; from an absolute magnitude of H = 27.99 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.01 km.

Observation record and orbit quality

The current orbit solution is based on 15 observations and has a weighted RMS residual of 0.5875 arcseconds.

Condition code U = 7 signals a poorly constrained orbit, so its future path should be treated as provisional.

About these computed values

Orbital periods, perihelion and aphelion speeds, and diameter estimates on this page are computed by SpaceAtlas from the JPL SBDB orbital elements. They are derived quantities, not values copied from the source catalogue.
