2020 OZ2

2020 OZ2 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.959 AU it takes 2.74 yr to circle the Sun.

Orbit and dynamics

The path is an ellipse reaching 0.738 AU from the Sun at perihelion and 3.18 AU at aphelion, a radial span of 2.442 AU.

Applying Kepler's third law to a = 1.959 AU gives an orbital period of 2.74 yr, or about 1,001 days.

The high eccentricity (0.624) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

A steep inclination of 37.15° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 44.2 km/s at perihelion and falls to 10.2 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 = 21.5 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.18 km.

Observation record and orbit quality

The current orbit solution is based on 53 observations and has a weighted RMS residual of 0.4437 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.
