Orbit and dynamics

The path is an ellipse reaching 0.495 AU from the Sun at perihelion and 2.359 AU at aphelion, a radial span of 1.864 AU.

Applying Kepler's third law to a = 1.427 AU gives an orbital period of 1.70 yr, or about 623 days.

The high eccentricity (0.653) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

A steep inclination of 23.64° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 54.4 km/s at perihelion and falls to 11.4 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 = 21.03 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.22 km.

Observation record and orbit quality

The current orbit solution is based on 156 observations and has a weighted RMS residual of 0.5681 arcseconds.

Condition code U = 0 means the orbit is very well determined, leaving only a small uncertainty in the future ephemeris.

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.
