Orbit and dynamics
Between its closest point (0.878 AU) and its farthest (2.59 AU), the heliocentric distance changes by 1.712 AU over every revolution.
One full revolution takes 2.28 yr (834 days), computed from the semi-major axis of 1.734 AU.
The high eccentricity (0.494) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
A steep inclination of 32.22° carries it well above and below the ecliptic plane.
By the vis-viva equation its orbital speed rises to 38.8 km/s at perihelion and falls to 13.2 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 0.58 km, a value from direct size determination rather than from brightness alone.
A geometric albedo of 0.272 points to a comparatively bright, reflective surface.
Observation record and orbit quality
Astrometry from 191 individual observations underpins this orbit; the fit leaves an RMS residual of 0.486 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.
