Orbit and dynamics

The path is an ellipse reaching 0.652 AU from the Sun at perihelion and 1.04 AU at aphelion, a radial span of 0.388 AU.

Applying Kepler's third law to a = 0.846 AU gives an orbital period of 0.78 yr, or about 284 days.

An eccentricity of 0.229 makes the orbit moderately elongated.

The orbital plane is tilted 13.93° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 40.9 km/s at perihelion and falls to 25.6 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 = 24.04 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.06 km.

Observation record and orbit quality

The current orbit solution is based on 68 observations and has a weighted RMS residual of 0.4792 arcseconds.

Condition code U = 6 indicates a moderately constrained orbit; predictions decades ahead still carry noticeable uncertainty.

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.
