Orbit and dynamics
The path is an ellipse reaching 1.011 AU from the Sun at perihelion and 1.281 AU at aphelion, a radial span of 0.27 AU.
Applying Kepler's third law to a = 1.146 AU gives an orbital period of 1.23 yr, or about 448 days.
An eccentricity of 0.118 makes the orbit moderately elongated.
The orbital plane is tilted 7.32° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 31.3 km/s at perihelion and falls to 24.7 km/s at aphelion.
Size and surface
No direct size measurement is available; from an absolute magnitude of H = 25.47 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 363 observations and has a weighted RMS residual of 0.3277 arcseconds.
Condition code U = 4 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.
