Orbit and dynamics
Between its closest point (0.861 AU) and its farthest (1.709 AU), the heliocentric distance changes by 0.848 AU over every revolution.
One full revolution takes 1.46 yr (532 days), computed from the semi-major axis of 1.285 AU.
An eccentricity of 0.33 makes the orbit moderately elongated.
A steep inclination of 34.52° carries it well above and below the ecliptic plane.
By the vis-viva equation its orbital speed rises to 37 km/s at perihelion and falls to 18.7 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 0.43 km, a value from direct size determination rather than from brightness alone.
A geometric albedo of 0.217 points to a comparatively bright, reflective surface.
Observation record and orbit quality
Astrometry from 327 individual observations underpins this orbit; the fit leaves an RMS residual of 0.5553 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.
