Orbit and dynamics
The path is an ellipse reaching 0.701 AU from the Sun at perihelion and 1.639 AU at aphelion, a radial span of 0.938 AU.
Applying Kepler's third law to a = 1.17 AU gives an orbital period of 1.27 yr, or about 462 days.
The high eccentricity (0.401) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
The orbital plane is tilted 13.33° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 42.1 km/s at perihelion and falls to 18 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 = 22.78 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.1 km.
Observation record and orbit quality
The current orbit solution is based on 122 observations and has a weighted RMS residual of 0.4602 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.
