Orbit and dynamics

Between its closest point (1.013 AU) and its farthest (1.733 AU), the heliocentric distance changes by 0.72 AU over every revolution.

One full revolution takes 1.61 yr (588 days), computed from the semi-major axis of 1.373 AU.

An eccentricity of 0.263 makes the orbit moderately elongated.

A steep inclination of 26.99° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 33.2 km/s at perihelion and falls to 19.4 km/s at aphelion.

Size and surface

No direct size measurement is available; from an absolute magnitude of H = 23.8 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.06 km.

Observation record and orbit quality

Astrometry from 47 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4356 arcseconds.

Condition code U = 7 signals a poorly constrained orbit, so its future path should be treated as provisional.

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.
