Orbit and dynamics

Between its closest point (1.029 AU) and its farthest (1.194 AU), the heliocentric distance changes by 0.165 AU over every revolution.

One full revolution takes 1.17 yr (428 days), computed from the semi-major axis of 1.111 AU.

With e = 0.074, the orbit is close to circular.

The orbital plane is tilted 8.21° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 30.4 km/s at perihelion and falls to 26.2 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 = 26.8 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.02 km.

Observation record and orbit quality

Astrometry from 17 individual observations underpins this orbit; the fit leaves an RMS residual of 0.412 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.
