Orbit and dynamics

The path is an ellipse reaching 1.016 AU from the Sun at perihelion and 2.336 AU at aphelion, a radial span of 1.32 AU.

Applying Kepler's third law to a = 1.676 AU gives an orbital period of 2.17 yr, or about 793 days.

An eccentricity of 0.394 makes the orbit moderately elongated.

The orbital plane is tilted 17.27° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 34.9 km/s at perihelion and falls to 15.2 km/s at aphelion.

Size and surface

The measured diameter is 0.76 km, a value from direct size determination rather than from brightness alone.

A geometric albedo of 0.224 points to a comparatively bright, reflective surface.

Observation record and orbit quality

The current orbit solution is based on 977 observations and has a weighted RMS residual of 0.4462 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.
