Orbit and dynamics

Between its closest point (0.373 AU) and its farthest (1.083 AU), the heliocentric distance changes by 0.71 AU over every revolution.

One full revolution takes 0.62 yr (227 days), computed from the semi-major axis of 0.728 AU.

The high eccentricity (0.488) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

A steep inclination of 22.92° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 59.5 km/s at perihelion and falls to 20.5 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 = 26.1 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.02 km.

Observation record and orbit quality

Astrometry from 51 individual observations underpins this orbit; the fit leaves an RMS residual of 0.3091 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.
