Orbit and dynamics
Between its closest point (0.333 AU) and its farthest (1.006 AU), the heliocentric distance changes by 0.673 AU over every revolution.
One full revolution takes 0.55 yr (200 days), computed from the semi-major axis of 0.669 AU.
The high eccentricity (0.503) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
The orbital plane is tilted 8.85° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 63.3 km/s at perihelion and falls to 20.9 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 = 26.1 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.02 km.
Observation record and orbit quality
Astrometry from 37 individual observations underpins this orbit; the fit leaves an RMS residual of 0.61 arcseconds.
Condition code U = 7 signals a poorly constrained orbit, so its future path should be treated as provisional.
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.
