Orbit and dynamics

The path is an ellipse reaching 0.746 AU from the Sun at perihelion and 1.164 AU at aphelion, a radial span of 0.418 AU.

Applying Kepler's third law to a = 0.955 AU gives an orbital period of 0.93 yr, or about 341 days.

An eccentricity of 0.219 makes the orbit moderately elongated.

The orbital plane is tilted 5.99° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 38.1 km/s at perihelion and falls to 24.4 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

Neither a measured diameter nor a reliable absolute magnitude is available for 2016 CL323, so its physical size remains unconstrained.

Observation record and orbit quality

The current orbit solution is based on 20 observations and has a weighted RMS residual of 0.76 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.
