Orbit and dynamics

The path is an ellipse reaching 0.511 AU from the Sun at perihelion and 0.991 AU at aphelion, a radial span of 0.48 AU.

Applying Kepler's third law to a = 0.751 AU gives an orbital period of 0.65 yr, or about 238 days.

An eccentricity of 0.32 makes the orbit moderately elongated.

The orbital plane is tilted 8.7° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 47.9 km/s at perihelion and falls to 24.7 km/s at aphelion.

Size and surface

Neither a measured diameter nor a reliable absolute magnitude is available for 2016 CJ323, so its physical size remains unconstrained.

Observation record and orbit quality

The current orbit solution is based on 14 observations and has a weighted RMS residual of 1.95 arcseconds.

Condition code U = 9 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.
