Orbit and dynamics
The path is an ellipse reaching 1.005 AU from the Sun at perihelion and 1.201 AU at aphelion, a radial span of 0.196 AU.
Applying Kepler's third law to a = 1.103 AU gives an orbital period of 1.16 yr, or about 423 days.
With e = 0.089, the orbit is close to circular.
The orbital plane is tilted 15.01° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 31 km/s at perihelion and falls to 25.9 km/s at aphelion.
Size and surface
No direct size measurement is available; from an absolute magnitude of H = 24.6 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 167 observations and has a weighted RMS residual of 0.4452 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.
