Orbit and dynamics

Between its closest point (0.55 AU) and its farthest (1.644 AU), the heliocentric distance changes by 1.094 AU over every revolution.

One full revolution takes 1.15 yr (420 days), computed from the semi-major axis of 1.097 AU.

The high eccentricity (0.498) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

A steep inclination of 27.85° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 49.2 km/s at perihelion and falls to 16.5 km/s at aphelion.

Because q < 1 AU and Q > 1 AU, this orbit geometrically intersects the region of Earth's orbit.

Size and surface

No direct size measurement is available; from an absolute magnitude of H = 22.58 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.11 km.

Observation record and orbit quality

Astrometry from 123 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4367 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.
