Orbit and dynamics
The path is an ellipse reaching 0.468 AU from the Sun at perihelion and 1.44 AU at aphelion, a radial span of 0.972 AU.
Applying Kepler's third law to a = 0.954 AU gives an orbital period of 0.93 yr, or about 340 days.
The high eccentricity (0.509) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
A steep inclination of 22.63° carries it well above and below the ecliptic plane.
By the vis-viva equation its orbital speed rises to 53.5 km/s at perihelion and falls to 17.4 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 0.59 km, a value from direct size determination rather than from brightness alone.
Its geometric albedo of 0.087 indicates a very dark, carbonaceous-type surface.
Observation record and orbit quality
The current orbit solution is based on 224 observations and has a weighted RMS residual of 0.4641 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.
