Orbit and dynamics

The path is an ellipse reaching 0.854 AU from the Sun at perihelion and 2.538 AU at aphelion, a radial span of 1.684 AU.

Applying Kepler's third law to a = 1.696 AU gives an orbital period of 2.21 yr, or about 807 days.

The high eccentricity (0.496) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

Its inclination of 4.77° keeps it close to the plane of the ecliptic.

By the vis-viva equation its orbital speed rises to 39.4 km/s at perihelion and falls to 13.3 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 = 23.2 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.08 km.

Observation record and orbit quality

The current orbit solution is based on 23 observations and has a weighted RMS residual of 0.8355 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.
