Orbit and dynamics
The path is an ellipse reaching 1.011 AU from the Sun at perihelion and 1.971 AU at aphelion, a radial span of 0.96 AU.
Applying Kepler's third law to a = 1.491 AU gives an orbital period of 1.82 yr, or about 665 days.
An eccentricity of 0.322 makes the orbit moderately elongated.
Its inclination of 3.11° 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 17.5 km/s at aphelion.
Size and surface
No direct size measurement is available; from an absolute magnitude of H = 25.5 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 146 observations and has a weighted RMS residual of 0.4038 arcseconds.
Condition code U = 6 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.
