Orbit and dynamics

Between its closest point (1.002 AU) and its farthest (2.216 AU), the heliocentric distance changes by 1.214 AU over every revolution.

One full revolution takes 2.04 yr (745 days), computed from the semi-major axis of 1.609 AU.

An eccentricity of 0.377 makes the orbit moderately elongated.

The orbital plane is tilted 15.06° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 34.9 km/s at perihelion and falls to 15.8 km/s at aphelion.

Size and surface

No direct size measurement is available; from an absolute magnitude of H = 24.2 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.05 km.

Observation record and orbit quality

Astrometry from 20 individual observations underpins this orbit; the fit leaves an RMS residual of 0.5539 arcseconds.

Condition code U = 9 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.
