Orbit and dynamics
The path is an ellipse reaching 0.987 AU from the Sun at perihelion and 1.467 AU at aphelion, a radial span of 0.48 AU.
Applying Kepler's third law to a = 1.227 AU gives an orbital period of 1.36 yr, or about 496 days.
An eccentricity of 0.195 makes the orbit moderately elongated.
The orbital plane is tilted 15.37° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 32.8 km/s at perihelion and falls to 22.1 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 = 22.4 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.12 km.
Observation record and orbit quality
The current orbit solution is based on 32 observations and has a weighted RMS residual of 0.6051 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.
