2022 RH

2022 RH belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.801 AU it takes 2.42 yr to circle the Sun.

Orbit and dynamics

The path is an ellipse reaching 0.85 AU from the Sun at perihelion and 2.752 AU at aphelion, a radial span of 1.902 AU.

Applying Kepler's third law to a = 1.801 AU gives an orbital period of 2.42 yr, or about 883 days.

The high eccentricity (0.528) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

A steep inclination of 20.26° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 39.9 km/s at perihelion and falls to 12.3 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 = 23.04 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.09 km.

Observation record and orbit quality

The current orbit solution is based on 22 observations and has a weighted RMS residual of 0.5244 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.
