Orbit and dynamics
Between its closest point (1.158 AU) and its farthest (4.273 AU), the heliocentric distance changes by 3.115 AU over every revolution.
One full revolution takes 4.47 yr (1,634 days), computed from the semi-major axis of 2.715 AU.
The high eccentricity (0.574) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
The orbital plane is tilted 11.91° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 34.7 km/s at perihelion and falls to 9.4 km/s at aphelion.
Its perihelion lies just outside Earth's orbit, which is why it is classed as Earth-approaching rather than Earth-crossing.
Size and surface
No direct size measurement is available; from an absolute magnitude of H = 22.26 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.13 km.
Observation record and orbit quality
Astrometry from 32 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4934 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.
