Orbit and dynamics

The path is an ellipse reaching 0.426 AU from the Sun at perihelion and 1.073 AU at aphelion, a radial span of 0.647 AU.

Applying Kepler's third law to a = 0.749 AU gives an orbital period of 0.65 yr, or about 237 days.

The high eccentricity (0.432) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

The orbital plane is tilted 19.8° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 54.6 km/s at perihelion and falls to 21.7 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 = 27.94 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.01 km.

Observation record and orbit quality

The current orbit solution is based on 103 observations and has a weighted RMS residual of 0.2279 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.
