Orbit and dynamics
The path is an ellipse reaching 0.969 AU from the Sun at perihelion and 1.358 AU at aphelion, a radial span of 0.389 AU.
Applying Kepler's third law to a = 1.164 AU gives an orbital period of 1.26 yr, or about 459 days.
An eccentricity of 0.167 makes the orbit moderately elongated.
A steep inclination of 23.52° carries it well above and below the ecliptic plane.
By the vis-viva equation its orbital speed rises to 32.7 km/s at perihelion and falls to 23.3 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 = 25.31 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.03 km.
Observation record and orbit quality
The current orbit solution is based on 25 observations and has a weighted RMS residual of 0.6382 arcseconds.
Condition code U = 0 means the orbit is very well determined, leaving only a small uncertainty in the future ephemeris.
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.
