Orbit and dynamics

Between its closest point (1.006 AU) and its farthest (1.538 AU), the heliocentric distance changes by 0.532 AU over every revolution.

One full revolution takes 1.43 yr (524 days), computed from the semi-major axis of 1.272 AU.

An eccentricity of 0.209 makes the orbit moderately elongated.

The orbital plane is tilted 9.93° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 32.7 km/s at perihelion and falls to 21.4 km/s at aphelion.

Size and surface

No direct size measurement is available; from an absolute magnitude of H = 23.48 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.07 km.

Observation record and orbit quality

Astrometry from 31 individual observations underpins this orbit; the fit leaves an RMS residual of 0.8077 arcseconds.

Condition code U = 6 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.
