Orbit and dynamics

Between its closest point (0.895 AU) and its farthest (1.291 AU), the heliocentric distance changes by 0.396 AU over every revolution.

One full revolution takes 1.14 yr (417 days), computed from the semi-major axis of 1.093 AU.

An eccentricity of 0.181 makes the orbit moderately elongated.

Its inclination of 1.5° keeps it close to the plane of the ecliptic.

By the vis-viva equation its orbital speed rises to 34.2 km/s at perihelion and falls to 23.7 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 = 24.97 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.04 km.

Observation record and orbit quality

Astrometry from 113 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4666 arcseconds.

Condition code U = 5 indicates a moderately constrained orbit; predictions decades ahead still carry noticeable uncertainty.

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.
