Orbit and dynamics

Between its closest point (1.093 AU) and its farthest (3.635 AU), the heliocentric distance changes by 2.542 AU over every revolution.

One full revolution takes 3.63 yr (1,328 days), computed from the semi-major axis of 2.364 AU.

The high eccentricity (0.538) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

The orbital plane is tilted 14.81° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 35.3 km/s at perihelion and falls to 10.6 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 = 22.92 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.09 km.

Observation record and orbit quality

Astrometry from 7 individual observations underpins this orbit; the fit leaves an RMS residual of 0.3261 arcseconds.

Condition code U = 9 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.
