Orbit and dynamics
Between its closest point (0.379 AU) and its farthest (2.601 AU), the heliocentric distance changes by 2.222 AU over every revolution.
One full revolution takes 1.82 yr (664 days), computed from the semi-major axis of 1.49 AU.
The high eccentricity (0.746) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
Its inclination of 4.63° keeps it close to the plane of the ecliptic.
By the vis-viva equation its orbital speed rises to 63.9 km/s at perihelion and falls to 9.3 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 = 20.11 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.34 km.
Observation record and orbit quality
Astrometry from 98 individual observations underpins this orbit; the fit leaves an RMS residual of 0.7365 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.
