Orbit and dynamics

Between its closest point (0.833 AU) and its farthest (0.993 AU), the heliocentric distance changes by 0.16 AU over every revolution.

One full revolution takes 0.87 yr (319 days), computed from the semi-major axis of 0.913 AU.

With e = 0.087, the orbit is close to circular.

Its inclination of 0.1° keeps it close to the plane of the ecliptic.

By the vis-viva equation its orbital speed rises to 34 km/s at perihelion and falls to 28.6 km/s at aphelion.

Size and surface

No direct size measurement is available; from an absolute magnitude of H = 28.71 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.01 km.

Observation record and orbit quality

Astrometry from 55 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4723 arcseconds.

Condition code U = 5 indicates a moderately constrained orbit; predictions decades ahead still carry noticeable uncertainty.

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.
