Orbit and dynamics

Between its closest point (1.06 AU) and its farthest (3.676 AU), the heliocentric distance changes by 2.616 AU over every revolution.

One full revolution takes 3.64 yr (1,331 days), computed from the semi-major axis of 2.368 AU.

The high eccentricity (0.552) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

A steep inclination of 26.86° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 36 km/s at perihelion and falls to 10.4 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 = 20.31 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.31 km.

Observation record and orbit quality

Astrometry from 44 individual observations underpins this orbit; the fit leaves an RMS residual of 0.6452 arcseconds.

Condition code U = 3 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.
