Orbit and dynamics
Between its closest point (0.946 AU) and its farthest (4.267 AU), the heliocentric distance changes by 3.321 AU over every revolution.
One full revolution takes 4.21 yr (1,537 days), computed from the semi-major axis of 2.607 AU.
The high eccentricity (0.637) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
A steep inclination of 23.8° carries it well above and below the ecliptic plane.
By the vis-viva equation its orbital speed rises to 39.2 km/s at perihelion and falls to 8.7 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 = 21.6 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.17 km.
Observation record and orbit quality
Astrometry from 84 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4707 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.
