Orbit and dynamics
Between its closest point (0.445 AU) and its farthest (1.08 AU), the heliocentric distance changes by 0.635 AU over every revolution.
One full revolution takes 0.67 yr (243 days), computed from the semi-major axis of 0.762 AU.
The high eccentricity (0.416) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
Its inclination of 2.19° keeps it close to the plane of the ecliptic.
By the vis-viva equation its orbital speed rises to 53.1 km/s at perihelion and falls to 21.9 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 = 26.28 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.02 km.
Observation record and orbit quality
Astrometry from 55 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4833 arcseconds.
Condition code U = 0 means the orbit is very well determined, leaving only a small uncertainty in the future ephemeris.
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.
