Orbit and dynamics

The path is an ellipse reaching 0.716 AU from the Sun at perihelion and 1.01 AU at aphelion, a radial span of 0.294 AU.

Applying Kepler's third law to a = 0.863 AU gives an orbital period of 0.80 yr, or about 293 days.

An eccentricity of 0.17 makes the orbit moderately elongated.

The orbital plane is tilted 10.54° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 38.1 km/s at perihelion and falls to 27 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 = 28.29 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.01 km.

Observation record and orbit quality

The current orbit solution is based on 5 observations and has a weighted RMS residual of 0.5409 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.
