Orbit and dynamics

The path is an ellipse reaching 0.183 AU from the Sun at perihelion and 3.501 AU at aphelion, a radial span of 3.318 AU.

Applying Kepler's third law to a = 1.842 AU gives an orbital period of 2.50 yr, or about 913 days.

The high eccentricity (0.901) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

The orbital plane is tilted 12.76° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 96 km/s at perihelion and falls to 5 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 = 18.21 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.81 km.

Observation record and orbit quality

The current orbit solution is based on 644 observations and has a weighted RMS residual of 0.4571 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.
