Orbit and dynamics
The path is an ellipse reaching 1.138 AU from the Sun at perihelion and 4.565 AU at aphelion, a radial span of 3.427 AU.
Applying Kepler's third law to a = 2.852 AU gives an orbital period of 4.82 yr, or about 1,759 days.
The high eccentricity (0.601) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
A steep inclination of 21.34° carries it well above and below the ecliptic plane.
By the vis-viva equation its orbital speed rises to 35.3 km/s at perihelion and falls to 8.8 km/s at aphelion.
Its perihelion lies just outside Earth's orbit, which is why it is classed as Earth-approaching rather than Earth-crossing.
Size and surface
The measured diameter is 0.73 km, a value from direct size determination rather than from brightness alone.
Its geometric albedo of 0.013 indicates a very dark, carbonaceous-type surface.
Observation record and orbit quality
The current orbit solution is based on 42 observations and has a weighted RMS residual of 0.4296 arcseconds.
Condition code U = 7 signals a poorly constrained orbit, so its future path should be treated as provisional.
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.
