Orbit and dynamics

The path is an ellipse reaching 0.865 AU from the Sun at perihelion and 1.708 AU at aphelion, a radial span of 0.843 AU.

Applying Kepler's third law to a = 1.286 AU gives an orbital period of 1.46 yr, or about 533 days.

An eccentricity of 0.328 makes the orbit moderately elongated.

A steep inclination of 46.42° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 36.9 km/s at perihelion and falls to 18.7 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 = 20.84 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.24 km.

Observation record and orbit quality

The current orbit solution is based on 29 observations and has a weighted RMS residual of 0.4472 arcseconds.

Condition code U = 1 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.
