Orbit and dynamics
The path is an ellipse reaching 1.017 AU from the Sun at perihelion and 2.647 AU at aphelion, a radial span of 1.63 AU.
Applying Kepler's third law to a = 1.832 AU gives an orbital period of 2.48 yr, or about 906 days.
The high eccentricity (0.445) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
The orbital plane is tilted 16.22° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 35.5 km/s at perihelion and falls to 13.6 km/s at aphelion.
Size and surface
The measured diameter is 0.84 km, a value from direct size determination rather than from brightness alone.
Its geometric albedo of 0.023 indicates a very dark, carbonaceous-type surface.
Observation record and orbit quality
The current orbit solution is based on 243 observations and has a weighted RMS residual of 0.4167 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.
