Orbit and dynamics
The path is an ellipse reaching 0.345 AU from the Sun at perihelion and 1.034 AU at aphelion, a radial span of 0.689 AU.
Applying Kepler's third law to a = 0.689 AU gives an orbital period of 0.57 yr, or about 209 days.
The high eccentricity (0.499) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
Its inclination of 2.81° keeps it close to the plane of the ecliptic.
By the vis-viva equation its orbital speed rises to 62.1 km/s at perihelion and falls to 20.7 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 = 26.06 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.02 km.
Observation record and orbit quality
The current orbit solution is based on 53 observations and has a weighted RMS residual of 0.4703 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.
