Orbit and dynamics
Between its closest point (0.707 AU) and its farthest (1.073 AU), the heliocentric distance changes by 0.366 AU over every revolution.
One full revolution takes 0.84 yr (307 days), computed from the semi-major axis of 0.89 AU.
An eccentricity of 0.206 makes the orbit moderately elongated.
A steep inclination of 23.06° carries it well above and below the ecliptic plane.
By the vis-viva equation its orbital speed rises to 38.9 km/s at perihelion and falls to 25.6 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 = 26.52 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.02 km.
Observation record and orbit quality
Astrometry from 40 individual observations underpins this orbit; the fit leaves an RMS residual of 0.509 arcseconds.
Condition code U = 6 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.
