Orbit and dynamics
The path is an ellipse reaching 0.195 AU from the Sun at perihelion and 2.889 AU at aphelion, a radial span of 2.694 AU.
Applying Kepler's third law to a = 1.542 AU gives an orbital period of 1.91 yr, or about 699 days.
The high eccentricity (0.873) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
Its inclination of 2.29° keeps it close to the plane of the ecliptic.
By the vis-viva equation its orbital speed rises to 92.3 km/s at perihelion and falls to 6.2 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
The measured diameter is 1.06 km, a value from direct size determination rather than from brightness alone.
Its geometric albedo of 0.074 indicates a very dark, carbonaceous-type surface.
Observation record and orbit quality
The current orbit solution is based on 1,501 observations and has a weighted RMS residual of 0.2631 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.
