Orbit and dynamics
Between its closest point (0.971 AU) and its farthest (3.943 AU), the heliocentric distance changes by 2.972 AU over every revolution.
One full revolution takes 3.85 yr (1,407 days), computed from the semi-major axis of 2.457 AU.
The high eccentricity (0.605) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
Its inclination of 4.03° keeps it close to the plane of the ecliptic.
By the vis-viva equation its orbital speed rises to 38.3 km/s at perihelion and falls to 9.4 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
The measured diameter is 0.11 km, a value from direct size determination rather than from brightness alone.
A geometric albedo of 0.23 points to a comparatively bright, reflective surface.
Observation record and orbit quality
Astrometry from 73 individual observations underpins this orbit; the fit leaves an RMS residual of 0.5064 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.
