Orbit and dynamics
The path is an ellipse reaching 0.711 AU from the Sun at perihelion and 1.231 AU at aphelion, a radial span of 0.52 AU.
Applying Kepler's third law to a = 0.971 AU gives an orbital period of 0.96 yr, or about 349 days.
An eccentricity of 0.267 makes the orbit moderately elongated.
A steep inclination of 21.71° carries it well above and below the ecliptic plane.
By the vis-viva equation its orbital speed rises to 39.8 km/s at perihelion and falls to 23 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 = 24.73 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.04 km.
Observation record and orbit quality
The current orbit solution is based on 25 observations and has a weighted RMS residual of 0.5139 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.
