Orbit and dynamics

The path is an ellipse reaching 0.84 AU from the Sun at perihelion and 1.518 AU at aphelion, a radial span of 0.678 AU.

Applying Kepler's third law to a = 1.179 AU gives an orbital period of 1.28 yr, or about 468 days.

An eccentricity of 0.288 makes the orbit moderately elongated.

A steep inclination of 27.71° 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 20.4 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 = 20.42 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.29 km.

Observation record and orbit quality

The current orbit solution is based on 144 observations and has a weighted RMS residual of 0.5733 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.
