Orbit and dynamics
The path is an ellipse reaching 1.012 AU from the Sun at perihelion and 1.762 AU at aphelion, a radial span of 0.75 AU.
Applying Kepler's third law to a = 1.387 AU gives an orbital period of 1.63 yr, or about 597 days.
An eccentricity of 0.27 makes the orbit moderately elongated.
Its inclination of 2.46° keeps it close to the plane of the ecliptic.
By the vis-viva equation its orbital speed rises to 33.4 km/s at perihelion and falls to 19.2 km/s at aphelion.
Size and surface
No direct size measurement is available; from an absolute magnitude of H = 24.92 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 28 observations and has a weighted RMS residual of 0.4808 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.
