Orbit and dynamics

Between its closest point (0.668 AU) and its farthest (1.069 AU), the heliocentric distance changes by 0.401 AU over every revolution.

One full revolution takes 0.81 yr (296 days), computed from the semi-major axis of 0.869 AU.

An eccentricity of 0.231 makes the orbit moderately elongated.

A steep inclination of 21.08° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 40.4 km/s at perihelion and falls to 25.3 km/s at aphelion.

Because q < 1 AU and Q > 1 AU, this orbit geometrically intersects the region of Earth's orbit.

Size and surface

No direct size measurement is available; from an absolute magnitude of H = 24.51 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.04 km.

Observation record and orbit quality

Astrometry from 31 individual observations underpins this orbit; the fit leaves an RMS residual of 0.3926 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.
