Orbit and dynamics
The path is an ellipse reaching 0.64 AU from the Sun at perihelion and 1.035 AU at aphelion, a radial span of 0.395 AU.
Applying Kepler's third law to a = 0.837 AU gives an orbital period of 0.77 yr, or about 280 days.
An eccentricity of 0.236 makes the orbit moderately elongated.
Its inclination of 3.95° keeps it close to the plane of the ecliptic.
By the vis-viva equation its orbital speed rises to 41.4 km/s at perihelion and falls to 25.6 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 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 16 observations and has a weighted RMS residual of 0.4997 arcseconds.
Condition code U = 7 signals a poorly constrained orbit, so its future path should be treated as provisional.
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.
