Orbit and dynamics
The path is an ellipse reaching 0.737 AU from the Sun at perihelion and 1.807 AU at aphelion, a radial span of 1.07 AU.
Applying Kepler's third law to a = 1.272 AU gives an orbital period of 1.43 yr, or about 524 days.
The high eccentricity (0.42) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
The orbital plane is tilted 9.5° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 41.4 km/s at perihelion and falls to 16.9 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 = 24.55 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.04 km.
Observation record and orbit quality
The current orbit solution is based on 58 observations and has a weighted RMS residual of 0.4464 arcseconds.
Condition code U = 3 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.
