Orbit and dynamics
The path is an ellipse reaching 0.853 AU from the Sun at perihelion and 1.095 AU at aphelion, a radial span of 0.242 AU.
Applying Kepler's third law to a = 0.974 AU gives an orbital period of 0.96 yr, or about 351 days.
An eccentricity of 0.124 makes the orbit moderately elongated.
Its inclination of 0.62° keeps it close to the plane of the ecliptic.
By the vis-viva equation its orbital speed rises to 34.2 km/s at perihelion and falls to 26.6 km/s at aphelion.
Because q < 1 AU and Q > 1 AU, this orbit geometrically intersects the region of Earth's orbit.
Size and surface
No direct size measurement is available; from an absolute magnitude of H = 26.2 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.02 km.
Observation record and orbit quality
The current orbit solution is based on 110 observations and has a weighted RMS residual of 0.4163 arcseconds.
Condition code U = 3 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.
