Orbit and dynamics
The path is an ellipse reaching 0.441 AU from the Sun at perihelion and 1.037 AU at aphelion, a radial span of 0.596 AU.
Applying Kepler's third law to a = 0.739 AU gives an orbital period of 0.64 yr, or about 232 days.
The high eccentricity (0.404) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
The orbital plane is tilted 9.69° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 53.1 km/s at perihelion and falls to 22.6 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 = 26.35 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 85 observations and has a weighted RMS residual of 0.4571 arcseconds.
Condition code U = 0 means the orbit is very well determined, leaving only a small uncertainty in the future ephemeris.
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.
