2020 UX

2020 UX belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.214 AU it takes 1.34 yr to circle the Sun.

Orbit and dynamics

The path is an ellipse reaching 0.827 AU from the Sun at perihelion and 1.601 AU at aphelion, a radial span of 0.774 AU.

Applying Kepler's third law to a = 1.214 AU gives an orbital period of 1.34 yr, or about 489 days.

An eccentricity of 0.319 makes the orbit moderately elongated.

Its inclination of 1.92° keeps it close to the plane of the ecliptic.

By the vis-viva equation its orbital speed rises to 37.6 km/s at perihelion and falls to 19.4 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

Neither a measured diameter nor a reliable absolute magnitude is available for 2020 UX, so its physical size remains unconstrained.

Observation record and orbit quality

The current orbit solution is based on 15 observations and has a weighted RMS residual of 0.9395 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.
