Orbit and dynamics
Between its closest point (1.011 AU) and its farthest (3.349 AU), the heliocentric distance changes by 2.338 AU over every revolution.
One full revolution takes 3.22 yr (1,176 days), computed from the semi-major axis of 2.18 AU.
The high eccentricity (0.536) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
The orbital plane is tilted 7.27° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 36.7 km/s at perihelion and falls to 11.1 km/s at aphelion.
Size and surface
The measured diameter is 0.09 km, a value from direct size determination rather than from brightness alone.
Its geometric albedo of 0.092 indicates a very dark, carbonaceous-type surface.
Observation record and orbit quality
Astrometry from 100 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4103 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.
