Orbit and dynamics
The path is an ellipse reaching 0.431 AU from the Sun at perihelion and 0.959 AU at aphelion, a radial span of 0.528 AU.
Applying Kepler's third law to a = 0.695 AU gives an orbital period of 0.58 yr, or about 212 days.
An eccentricity of 0.38 makes the orbit moderately elongated.
A steep inclination of 24.31° carries it well above and below the ecliptic plane.
By the vis-viva equation its orbital speed rises to 53.3 km/s at perihelion and falls to 24 km/s at aphelion.
Size and surface
No direct size measurement is available; from an absolute magnitude of H = 18.48 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.72 km.
Observation record and orbit quality
The current orbit solution is based on 449 observations and has a weighted RMS residual of 0.4355 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.
