2020 AV1

2020 AV1 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.121 AU it takes 1.19 yr to circle the Sun.

Orbit and dynamics

The path is an ellipse reaching 0.82 AU from the Sun at perihelion and 1.422 AU at aphelion, a radial span of 0.602 AU.

Applying Kepler's third law to a = 1.121 AU gives an orbital period of 1.19 yr, or about 434 days.

An eccentricity of 0.268 makes the orbit moderately elongated.

The orbital plane is tilted 17.34° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 37 km/s at perihelion and falls to 21.4 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

No direct size measurement is available; from an absolute magnitude of H = 26.09 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.02 km.

Observation record and orbit quality

The current orbit solution is based on 47 observations and has a weighted RMS residual of 0.7033 arcseconds.

Condition code U = 8 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.
