Orbit and dynamics
Between its closest point (0.804 AU) and its farthest (2.612 AU), the heliocentric distance changes by 1.808 AU over every revolution.
One full revolution takes 2.23 yr (815 days), computed from the semi-major axis of 1.708 AU.
The high eccentricity (0.529) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
A steep inclination of 44.77° carries it well above and below the ecliptic plane.
By the vis-viva equation its orbital speed rises to 41.1 km/s at perihelion and falls to 12.6 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 0.39 km, a value from direct size determination rather than from brightness alone.
A geometric albedo of 0.137 points to a comparatively bright, reflective surface.
Observation record and orbit quality
Astrometry from 90 individual observations underpins this orbit; the fit leaves an RMS residual of 0.5154 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.
