Orbit and dynamics

The path is an ellipse reaching 0.362 AU from the Sun at perihelion and 1.336 AU at aphelion, a radial span of 0.974 AU.

Applying Kepler's third law to a = 0.849 AU gives an orbital period of 0.78 yr, or about 286 days.

The high eccentricity (0.574) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

The orbital plane is tilted 13.65° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 62.1 km/s at perihelion and falls to 16.8 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 = 23.81 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.06 km.

Observation record and orbit quality

The current orbit solution is based on 38 observations and has a weighted RMS residual of 0.645 arcseconds.

Condition code U = 7 signals a poorly constrained orbit, so its future path should be treated as provisional.

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.
