Orbit and dynamics
The path is an ellipse reaching 0.329 AU from the Sun at perihelion and 0.941 AU at aphelion, a radial span of 0.612 AU.
Applying Kepler's third law to a = 0.635 AU gives an orbital period of 0.51 yr, or about 185 days.
The high eccentricity (0.482) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
The orbital plane is tilted 19.85° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 63.2 km/s at perihelion and falls to 22.1 km/s at aphelion.
Size and surface
No direct size measurement is available; from an absolute magnitude of H = 18.14 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.84 km.
Observation record and orbit quality
The current orbit solution is based on 296 observations and has a weighted RMS residual of 0.4755 arcseconds.
Condition code U = 1 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.
