Orbit and dynamics
Between its closest point (0.54 AU) and its farthest (1.285 AU), the heliocentric distance changes by 0.745 AU over every revolution.
One full revolution takes 0.87 yr (318 days), computed from the semi-major axis of 0.912 AU.
The high eccentricity (0.408) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
The orbital plane is tilted 12.27° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 48.1 km/s at perihelion and falls to 20.2 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 = 25.3 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.03 km.
Observation record and orbit quality
Astrometry from 39 individual observations underpins this orbit; the fit leaves an RMS residual of 0.5188 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.
