Orbit and dynamics
Between its closest point (0.387 AU) and its farthest (1.049 AU), the heliocentric distance changes by 0.662 AU over every revolution.
One full revolution takes 0.61 yr (222 days), computed from the semi-major axis of 0.718 AU.
The high eccentricity (0.461) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
The orbital plane is tilted 7.94° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 57.9 km/s at perihelion and falls to 21.3 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 = 26.95 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.01 km.
Observation record and orbit quality
Astrometry from 38 individual observations underpins this orbit; the fit leaves an RMS residual of 0.3617 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.
