Orbit and dynamics
Between its closest point (0.573 AU) and its farthest (1.154 AU), the heliocentric distance changes by 0.581 AU over every revolution.
One full revolution takes 0.80 yr (293 days), computed from the semi-major axis of 0.864 AU.
An eccentricity of 0.337 makes the orbit moderately elongated.
A steep inclination of 26.54° carries it well above and below the ecliptic plane.
By the vis-viva equation its orbital speed rises to 45.5 km/s at perihelion and falls to 22.6 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 0.32 km, a value from direct size determination rather than from brightness alone.
A geometric albedo of 0.123 points to a comparatively bright, reflective surface.
Observation record and orbit quality
Astrometry from 264 individual observations underpins this orbit; the fit leaves an RMS residual of 0.5052 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.
