Orbit and dynamics

The path is an ellipse reaching 1.199 AU from the Sun at perihelion and 1.603 AU at aphelion, a radial span of 0.404 AU.

Applying Kepler's third law to a = 1.401 AU gives an orbital period of 1.66 yr, or about 606 days.

An eccentricity of 0.144 makes the orbit moderately elongated.

A steep inclination of 44.84° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 29.1 km/s at perihelion and falls to 21.8 km/s at aphelion.

Its perihelion lies just outside Earth's orbit, which is why it is classed as Earth-approaching rather than Earth-crossing.

Size and surface

The measured diameter is 0.37 km, a value from direct size determination rather than from brightness alone.

A geometric albedo of 0.205 points to a comparatively bright, reflective surface.

Observation record and orbit quality

The current orbit solution is based on 462 observations and has a weighted RMS residual of 0.5911 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.
