Orbit and dynamics

The path is an ellipse reaching 1.099 AU from the Sun at perihelion and 2.285 AU at aphelion, a radial span of 1.186 AU.

Applying Kepler's third law to a = 1.692 AU gives an orbital period of 2.20 yr, or about 804 days.

An eccentricity of 0.351 makes the orbit moderately elongated.

A steep inclination of 24.82° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 33 km/s at perihelion and falls to 15.9 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 = 23.11 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.08 km.

Observation record and orbit quality

The current orbit solution is based on 14 observations and has a weighted RMS residual of 0.414 arcseconds.

Condition code U = 9 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.
