Orbit and dynamics
The path is an ellipse reaching 1.067 AU from the Sun at perihelion and 4.369 AU at aphelion, a radial span of 3.302 AU.
Applying Kepler's third law to a = 2.718 AU gives an orbital period of 4.48 yr, or about 1,637 days.
The high eccentricity (0.608) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
A steep inclination of 20.79° carries it well above and below the ecliptic plane.
By the vis-viva equation its orbital speed rises to 36.6 km/s at perihelion and falls to 8.9 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 0.49 km, a value from direct size determination rather than from brightness alone.
A geometric albedo of 0.241 points to a comparatively bright, reflective surface.
Observation record and orbit quality
The current orbit solution is based on 98 observations and has a weighted RMS residual of 0.4293 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.
