2016 CZ30

2016 CZ30 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.077 AU it takes 1.12 yr to circle the Sun.

Orbit and dynamics

The path is an ellipse reaching 0.85 AU from the Sun at perihelion and 1.304 AU at aphelion, a radial span of 0.454 AU.

Applying Kepler's third law to a = 1.077 AU gives an orbital period of 1.12 yr, or about 408 days.

An eccentricity of 0.211 makes the orbit moderately elongated.

A steep inclination of 20.65° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 35.5 km/s at perihelion and falls to 23.2 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 = 25.7 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 97 observations and has a weighted RMS residual of 0.431 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.
