Orbit and dynamics
The path is an ellipse reaching 0.656 AU from the Sun at perihelion and 1.019 AU at aphelion, a radial span of 0.363 AU.
Applying Kepler's third law to a = 0.838 AU gives an orbital period of 0.77 yr, or about 280 days.
An eccentricity of 0.217 makes the orbit moderately elongated.
The orbital plane is tilted 13.08° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 40.6 km/s at perihelion and falls to 26.1 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 = 24.4 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.05 km.
Observation record and orbit quality
The current orbit solution is based on 59 observations and has a weighted RMS residual of 0.3913 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.
