Orbit and dynamics

The path is an ellipse reaching 0.858 AU from the Sun at perihelion and 1.071 AU at aphelion, a radial span of 0.213 AU.

Applying Kepler's third law to a = 0.965 AU gives an orbital period of 0.95 yr, or about 346 days.

An eccentricity of 0.11 makes the orbit moderately elongated.

The orbital plane is tilted 9.09° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 33.9 km/s at perihelion and falls to 27.1 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 = 25.3 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.03 km.

Observation record and orbit quality

The current orbit solution is based on 154 observations and has a weighted RMS residual of 0.3483 arcseconds.

Condition code U = 2 means the orbit is very well determined, leaving only a small uncertainty in the future ephemeris.

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.
