Orbit and dynamics

The path is an ellipse reaching 0.487 AU from the Sun at perihelion and 1.06 AU at aphelion, a radial span of 0.573 AU.

Applying Kepler's third law to a = 0.773 AU gives an orbital period of 0.68 yr, or about 248 days.

An eccentricity of 0.371 makes the orbit moderately elongated.

A steep inclination of 24.04° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 50 km/s at perihelion and falls to 23 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 = 25.02 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.04 km.

Observation record and orbit quality

The current orbit solution is based on 64 observations and has a weighted RMS residual of 0.3055 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.
