Orbit and dynamics
The path is an ellipse reaching 0.852 AU from the Sun at perihelion and 1.558 AU at aphelion, a radial span of 0.706 AU.
Applying Kepler's third law to a = 1.205 AU gives an orbital period of 1.32 yr, or about 483 days.
An eccentricity of 0.293 makes the orbit moderately elongated.
The orbital plane is tilted 14.44° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 36.7 km/s at perihelion and falls to 20.1 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 = 22.83 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.1 km.
Observation record and orbit quality
The current orbit solution is based on 170 observations and has a weighted RMS residual of 0.4117 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.
