Orbit and dynamics

Between its closest point (0.705 AU) and its farthest (2.605 AU), the heliocentric distance changes by 1.9 AU over every revolution.

One full revolution takes 2.13 yr (778 days), computed from the semi-major axis of 1.655 AU.

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

Its inclination of 1.2° keeps it close to the plane of the ecliptic.

By the vis-viva equation its orbital speed rises to 44.5 km/s at perihelion and falls to 12 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 = 20.11 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.34 km.

Observation record and orbit quality

Astrometry from 492 individual observations underpins this orbit; the fit leaves an RMS residual of 0.3943 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.
