Orbit and dynamics

Between its closest point (1.257 AU) and its farthest (2.89 AU), the heliocentric distance changes by 1.633 AU over every revolution.

One full revolution takes 2.98 yr (1,090 days), computed from the semi-major axis of 2.073 AU.

An eccentricity of 0.394 makes the orbit moderately elongated.

A steep inclination of 24.41° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 31.4 km/s at perihelion and falls to 13.6 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 = 21.32 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.19 km.

Observation record and orbit quality

Astrometry from 141 individual observations underpins this orbit; the fit leaves an RMS residual of 0.493 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.
