Orbit and dynamics

The path is an ellipse reaching 1.009 AU from the Sun at perihelion and 1.986 AU at aphelion, a radial span of 0.977 AU.

Applying Kepler's third law to a = 1.498 AU gives an orbital period of 1.83 yr, or about 670 days.

An eccentricity of 0.326 makes the orbit moderately elongated.

Its inclination of 3.64° keeps it close to the plane of the ecliptic.

By the vis-viva equation its orbital speed rises to 34.1 km/s at perihelion and falls to 17.3 km/s at aphelion.

Size and surface

No direct size measurement is available; from an absolute magnitude of H = 24.7 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.04 km.

Observation record and orbit quality

The current orbit solution is based on 63 observations and has a weighted RMS residual of 0.2893 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.
