Orbit and dynamics

Between its closest point (0.964 AU) and its farthest (1.934 AU), the heliocentric distance changes by 0.97 AU over every revolution.

One full revolution takes 1.74 yr (637 days), computed from the semi-major axis of 1.449 AU.

An eccentricity of 0.335 makes the orbit moderately elongated.

A steep inclination of 30.11° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 35 km/s at perihelion and falls to 17.5 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 = 24.2 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.05 km.

Observation record and orbit quality

Astrometry from 21 individual observations underpins this orbit; the fit leaves an RMS residual of 0.6087 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.
