Orbit and dynamics

Between its closest point (1.174 AU) and its farthest (3.304 AU), the heliocentric distance changes by 2.13 AU over every revolution.

One full revolution takes 3.35 yr (1,224 days), computed from the semi-major axis of 2.239 AU.

The high eccentricity (0.476) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

A steep inclination of 22.02° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 33.4 km/s at perihelion and falls to 11.9 km/s at aphelion.

Its perihelion lies just outside Earth's orbit, which is why it is classed as Earth-approaching rather than Earth-crossing.

Size and surface

No direct size measurement is available; from an absolute magnitude of H = 20.61 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.27 km.

Observation record and orbit quality

Astrometry from 124 individual observations underpins this orbit; the fit leaves an RMS residual of 0.3839 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.
