Orbit and dynamics

The path is an ellipse reaching 0.869 AU from the Sun at perihelion and 2.887 AU at aphelion, a radial span of 2.018 AU.

Applying Kepler's third law to a = 1.878 AU gives an orbital period of 2.57 yr, or about 940 days.

The high eccentricity (0.537) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

The orbital plane is tilted 5.16° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 39.6 km/s at perihelion and falls to 11.9 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

The measured diameter is 0.07 km, a value from direct size determination rather than from brightness alone.

A geometric albedo of 0.103 points to a comparatively bright, reflective surface.

Observation record and orbit quality

The current orbit solution is based on 54 observations and has a weighted RMS residual of 0.6193 arcseconds.

Condition code U = 8 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.
