Orbit and dynamics
The path is an ellipse reaching 1.01 AU from the Sun at perihelion and 1.649 AU at aphelion, a radial span of 0.639 AU.
Applying Kepler's third law to a = 1.33 AU gives an orbital period of 1.53 yr, or about 560 days.
An eccentricity of 0.24 makes the orbit moderately elongated.
The orbital plane is tilted 7.04° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 33 km/s at perihelion and falls to 20.2 km/s at aphelion.
Size and surface
The measured diameter is 0.09 km, a value from direct size determination rather than from brightness alone.
Its geometric albedo of 0.051 indicates a very dark, carbonaceous-type surface.
Observation record and orbit quality
The current orbit solution is based on 57 observations and has a weighted RMS residual of 0.4438 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.
