Orbit and dynamics
Between its closest point (0.49 AU) and its farthest (1.122 AU), the heliocentric distance changes by 0.632 AU over every revolution.
One full revolution takes 0.72 yr (264 days), computed from the semi-major axis of 0.806 AU.
An eccentricity of 0.392 makes the orbit moderately elongated.
A steep inclination of 33.04° carries it well above and below the ecliptic plane.
By the vis-viva equation its orbital speed rises to 50.2 km/s at perihelion and falls to 21.9 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
No direct size measurement is available; from an absolute magnitude of H = 24.54 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.04 km.
Observation record and orbit quality
Astrometry from 107 individual observations underpins this orbit; the fit leaves an RMS residual of 0.3924 arcseconds.
Condition code U = 7 signals a poorly constrained orbit, so its future path should be treated as provisional.
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.
