Orbit and dynamics
Between its closest point (0.704 AU) and its farthest (1.167 AU), the heliocentric distance changes by 0.463 AU over every revolution.
One full revolution takes 0.90 yr (330 days), computed from the semi-major axis of 0.935 AU.
An eccentricity of 0.247 makes the orbit moderately elongated.
A steep inclination of 22.82° carries it well above and below the ecliptic plane.
By the vis-viva equation its orbital speed rises to 39.6 km/s at perihelion and falls to 23.9 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 = 24.4 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.05 km.
Observation record and orbit quality
Astrometry from 31 individual observations underpins this orbit; the fit leaves an RMS residual of 0.5273 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.
