Orbit and dynamics

The path is an ellipse reaching 0.721 AU from the Sun at perihelion and 1.149 AU at aphelion, a radial span of 0.428 AU.

Applying Kepler's third law to a = 0.935 AU gives an orbital period of 0.90 yr, or about 330 days.

An eccentricity of 0.229 makes the orbit moderately elongated.

Its inclination of 0.38° keeps it close to the plane of the ecliptic.

By the vis-viva equation its orbital speed rises to 38.9 km/s at perihelion and falls to 24.4 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 = 26.58 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.02 km.

Observation record and orbit quality

The current orbit solution is based on 9 observations and has a weighted RMS residual of 0.2249 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.
