Orbit and dynamics

The path is an ellipse reaching 0.628 AU from the Sun at perihelion and 1.15 AU at aphelion, a radial span of 0.522 AU.

Applying Kepler's third law to a = 0.889 AU gives an orbital period of 0.84 yr, or about 306 days.

An eccentricity of 0.293 makes the orbit moderately elongated.

A steep inclination of 22.63° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 42.7 km/s at perihelion and falls to 23.4 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 = 21.02 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.22 km.

Observation record and orbit quality

The current orbit solution is based on 183 observations and has a weighted RMS residual of 0.4629 arcseconds.

Condition code U = 0 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.
