Orbit and dynamics

Between its closest point (1.03 AU) and its farthest (1.804 AU), the heliocentric distance changes by 0.774 AU over every revolution.

One full revolution takes 1.69 yr (616 days), computed from the semi-major axis of 1.417 AU.

An eccentricity of 0.273 makes the orbit moderately elongated.

The orbital plane is tilted 12.95° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 33.1 km/s at perihelion and falls to 18.9 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 = 26.85 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.02 km.

Observation record and orbit quality

Astrometry from 22 individual observations underpins this orbit; the fit leaves an RMS residual of 0.6159 arcseconds.

Condition code U = 8 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.
