2022 YZ2

2022 YZ2 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.669 AU it takes 2.16 yr to circle the Sun.

Orbit and dynamics

The path is an ellipse reaching 1.011 AU from the Sun at perihelion and 2.327 AU at aphelion, a radial span of 1.316 AU.

Applying Kepler's third law to a = 1.669 AU gives an orbital period of 2.16 yr, or about 788 days.

An eccentricity of 0.394 makes the orbit moderately elongated.

The orbital plane is tilted 7.63° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 35 km/s at perihelion and falls to 15.2 km/s at aphelion.

Size and surface

No direct size measurement is available; from an absolute magnitude of H = 23.43 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.07 km.

Observation record and orbit quality

The current orbit solution is based on 150 observations and has a weighted RMS residual of 0.531 arcseconds.

Condition code U = 5 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.
