Orbit and dynamics

Between its closest point (1.011 AU) and its farthest (1.528 AU), the heliocentric distance changes by 0.517 AU over every revolution.

One full revolution takes 1.43 yr (523 days), computed from the semi-major axis of 1.27 AU.

An eccentricity of 0.203 makes the orbit moderately elongated.

Its inclination of 3.59° keeps it close to the plane of the ecliptic.

By the vis-viva equation its orbital speed rises to 32.5 km/s at perihelion and falls to 21.5 km/s at aphelion.

Size and surface

No direct size measurement is available; from an absolute magnitude of H = 27.12 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.01 km.

Observation record and orbit quality

Astrometry from 50 individual observations underpins this orbit; the fit leaves an RMS residual of 0.3881 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.
