Orbit and dynamics

Between its closest point (1.116 AU) and its farthest (2.524 AU), the heliocentric distance changes by 1.408 AU over every revolution.

One full revolution takes 2.46 yr (897 days), computed from the semi-major axis of 1.82 AU.

An eccentricity of 0.387 makes the orbit moderately elongated.

The orbital plane is tilted 14.86° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 33.2 km/s at perihelion and falls to 14.7 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 = 23.53 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.07 km.

Observation record and orbit quality

Astrometry from 38 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4491 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.
