Orbit and dynamics
Between its closest point (0.7 AU) and its farthest (1.986 AU), the heliocentric distance changes by 1.286 AU over every revolution.
One full revolution takes 1.56 yr (568 days), computed from the semi-major axis of 1.343 AU.
The high eccentricity (0.479) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
Its inclination of 3.37° keeps it close to the plane of the ecliptic.
By the vis-viva equation its orbital speed rises to 43.3 km/s at perihelion and falls to 15.3 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 = 25.54 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.03 km.
Observation record and orbit quality
Astrometry from 141 individual observations underpins this orbit; the fit leaves an RMS residual of 0.2372 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.
