Orbit and dynamics

The path is an ellipse reaching 1.146 AU from the Sun at perihelion and 2.63 AU at aphelion, a radial span of 1.484 AU.

Applying Kepler's third law to a = 1.888 AU gives an orbital period of 2.59 yr, or about 948 days.

An eccentricity of 0.393 makes the orbit moderately elongated.

Its inclination of 1.43° keeps it close to the plane of the ecliptic.

By the vis-viva equation its orbital speed rises to 32.8 km/s at perihelion and falls to 14.3 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 = 23.1 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.09 km.

Observation record and orbit quality

The current orbit solution is based on 38 observations and has a weighted RMS residual of 0.7935 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.
