2022 UB13

2022 UB13 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.562 AU it takes 1.95 yr to circle the Sun.

Orbit and dynamics

The path is an ellipse reaching 0.99 AU from the Sun at perihelion and 2.134 AU at aphelion, a radial span of 1.144 AU.

Applying Kepler's third law to a = 1.562 AU gives an orbital period of 1.95 yr, or about 713 days.

An eccentricity of 0.366 makes the orbit moderately elongated.

The orbital plane is tilted 9.28° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 35 km/s at perihelion and falls to 16.2 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 = 29.92 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0 km.

Observation record and orbit quality

The current orbit solution is based on 58 observations and has a weighted RMS residual of 0.3097 arcseconds.

Condition code U = 6 indicates a moderately constrained orbit; predictions decades ahead still carry noticeable uncertainty.

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.
