Orbit and dynamics

The path is an ellipse reaching 0.279 AU from the Sun at perihelion and 3.479 AU at aphelion, a radial span of 3.2 AU.

Applying Kepler's third law to a = 1.879 AU gives an orbital period of 2.58 yr, or about 941 days.

The high eccentricity (0.852) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

The orbital plane is tilted 10.96° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 76.7 km/s at perihelion and falls to 6.2 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 = 20.44 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.29 km.

Observation record and orbit quality

The current orbit solution is based on 77 observations and has a weighted RMS residual of 0.4998 arcseconds.

Condition code U = 5 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.
