Orbit and dynamics
The path is an ellipse reaching 1.105 AU from the Sun at perihelion and 1.57 AU at aphelion, a radial span of 0.465 AU.
Applying Kepler's third law to a = 1.337 AU gives an orbital period of 1.55 yr, or about 565 days.
An eccentricity of 0.174 makes the orbit moderately elongated.
A steep inclination of 26.19° carries it well above and below the ecliptic plane.
By the vis-viva equation its orbital speed rises to 30.7 km/s at perihelion and falls to 21.6 km/s at aphelion.
Its perihelion lies just outside Earth's orbit, which is why it is classed as Earth-approaching rather than Earth-crossing.
Size and surface
No direct size measurement is available; from an absolute magnitude of H = 21 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.22 km.
Observation record and orbit quality
The current orbit solution is based on 87 observations and has a weighted RMS residual of 0.4492 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.
