Orbit and dynamics
The path is an ellipse reaching 1.005 AU from the Sun at perihelion and 3.811 AU at aphelion, a radial span of 2.806 AU.
Applying Kepler's third law to a = 2.408 AU gives an orbital period of 3.74 yr, or about 1,365 days.
The high eccentricity (0.583) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
The orbital plane is tilted 17.71° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 37.4 km/s at perihelion and falls to 9.9 km/s at aphelion.
Size and surface
The measured diameter is 0.19 km, a value from direct size determination rather than from brightness alone.
A geometric albedo of 0.314 points to a comparatively bright, reflective surface.
Observation record and orbit quality
The current orbit solution is based on 90 observations and has a weighted RMS residual of 0.5404 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.
