Orbit and dynamics
The path is an ellipse reaching 1.027 AU from the Sun at perihelion and 10.373 AU at aphelion, a radial span of 9.346 AU.
Applying Kepler's third law to a = 5.7 AU gives an orbital period of 13.6 yr, or about 4,971 days.
The high eccentricity (0.82) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
A steep inclination of 54.98° carries it well above and below the ecliptic plane.
By the vis-viva equation its orbital speed rises to 39.6 km/s at perihelion and falls to 3.9 km/s at aphelion.
Its Tisserand parameter with respect to Jupiter is T_J = 1.6, a standard discriminator between asteroidal and cometary dynamics.
Size and surface
The measured diameter is 4.5 km, a value from direct size determination rather than from brightness alone.
Observation record and orbit quality
The current orbit solution is based on 1,768 observations and has a weighted RMS residual of 0.6884 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.
