Orbit and dynamics

Between its closest point (0.63 AU) and its farthest (1.343 AU), the heliocentric distance changes by 0.713 AU over every revolution.

One full revolution takes 0.98 yr (358 days), computed from the semi-major axis of 0.986 AU.

An eccentricity of 0.362 makes the orbit moderately elongated.

Its inclination of 1.25° keeps it close to the plane of the ecliptic.

By the vis-viva equation its orbital speed rises to 43.8 km/s at perihelion and falls to 20.5 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 = 26.6 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.02 km.

Observation record and orbit quality

Astrometry from 27 individual observations underpins this orbit; the fit leaves an RMS residual of 0.696 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.
