2020 QZ1

2020 QZ1 is an Amor-type near-Earth asteroid that approaches Earth from beyond our orbit without crossing it, orbiting the Sun at 1.487 AU once every 1.81 yr.

Orbit and dynamics

The path is an ellipse reaching 1.028 AU from the Sun at perihelion and 1.946 AU at aphelion, a radial span of 0.918 AU.

Applying Kepler's third law to a = 1.487 AU gives an orbital period of 1.81 yr, or about 662 days.

An eccentricity of 0.309 makes the orbit moderately elongated.

The orbital plane is tilted 16.78° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 33.6 km/s at perihelion and falls to 17.8 km/s at aphelion.

Its perihelion lies just outside Earth's orbit, which is why it is classed as Earth-approaching rather than Earth-crossing.

Size and surface

No direct size measurement is available; from an absolute magnitude of H = 25.3 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.03 km.

Observation record and orbit quality

The current orbit solution is based on 33 observations and has a weighted RMS residual of 0.6194 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.
