Orbit and dynamics
Between its closest point (0.455 AU) and its farthest (1.303 AU), the heliocentric distance changes by 0.848 AU over every revolution.
One full revolution takes 0.82 yr (301 days), computed from the semi-major axis of 0.879 AU.
The high eccentricity (0.482) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
A steep inclination of 24.55° carries it well above and below the ecliptic plane.
By the vis-viva equation its orbital speed rises to 53.8 km/s at perihelion and falls to 18.8 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 = 22.74 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.1 km.
Observation record and orbit quality
Astrometry from 38 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4875 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.
