Orbit and dynamics

Between its closest point (1.128 AU) and its farthest (2.342 AU), the heliocentric distance changes by 1.214 AU over every revolution.

One full revolution takes 2.29 yr (835 days), computed from the semi-major axis of 1.735 AU.

An eccentricity of 0.35 makes the orbit moderately elongated.

A steep inclination of 40.83° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 32.6 km/s at perihelion and falls to 15.7 km/s at aphelion.

Its perihelion lies just outside Earth's orbit, which is why it is classed as Earth-approaching rather than Earth-crossing.

Size and surface

No direct size measurement is available; from an absolute magnitude of H = 22 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.14 km.

Observation record and orbit quality

Astrometry from 33 individual observations underpins this orbit; the fit leaves an RMS residual of 0.3652 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.
