Orbit and dynamics

Between its closest point (1.004 AU) and its farthest (1.286 AU), the heliocentric distance changes by 0.282 AU over every revolution.

One full revolution takes 1.23 yr (448 days), computed from the semi-major axis of 1.145 AU.

An eccentricity of 0.123 makes the orbit moderately elongated.

A steep inclination of 29.07° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 31.5 km/s at perihelion and falls to 24.6 km/s at aphelion.

Size and surface

No direct size measurement is available; from an absolute magnitude of H = 26.14 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.02 km.

Observation record and orbit quality

Astrometry from 16 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4697 arcseconds.

Condition code U = 8 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.
