Orbit and dynamics
The path is an ellipse reaching 0.59 AU from the Sun at perihelion and 1.956 AU at aphelion, a radial span of 1.366 AU.
Applying Kepler's third law to a = 1.273 AU gives an orbital period of 1.44 yr, or about 525 days.
The high eccentricity (0.537) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
A steep inclination of 30.64° carries it well above and below the ecliptic plane.
By the vis-viva equation its orbital speed rises to 48.1 km/s at perihelion and falls to 14.5 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 = 21.55 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.17 km.
Observation record and orbit quality
The current orbit solution is based on 63 observations and has a weighted RMS residual of 0.6105 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.
