Orbit and dynamics

The path is an ellipse reaching 0.463 AU from the Sun at perihelion and 1.095 AU at aphelion, a radial span of 0.632 AU.

Applying Kepler's third law to a = 0.779 AU gives an orbital period of 0.69 yr, or about 251 days.

The high eccentricity (0.405) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

The orbital plane is tilted 7.69° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 51.9 km/s at perihelion and falls to 21.9 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 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.09 km.

Observation record and orbit quality

The current orbit solution is based on 36 observations and has a weighted RMS residual of 0.378 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.
