Orbit and dynamics
Between its closest point (0.323 AU) and its farthest (3.569 AU), the heliocentric distance changes by 3.246 AU over every revolution.
One full revolution takes 2.71 yr (992 days), computed from the semi-major axis of 1.946 AU.
The high eccentricity (0.834) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
The orbital plane is tilted 17.74° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 71 km/s at perihelion and falls to 6.4 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 0.07 km, a value from direct size determination rather than from brightness alone.
A geometric albedo of 0.238 points to a comparatively bright, reflective surface.
Observation record and orbit quality
Astrometry from 111 individual observations underpins this orbit; the fit leaves an RMS residual of 0.5199 arcseconds.
Condition code U = 8 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.
