Orbit and dynamics
Between its closest point (0.923 AU) and its farthest (1.205 AU), the heliocentric distance changes by 0.282 AU over every revolution.
One full revolution takes 1.10 yr (401 days), computed from the semi-major axis of 1.064 AU.
An eccentricity of 0.133 makes the orbit moderately elongated.
A steep inclination of 29.15° carries it well above and below the ecliptic plane.
By the vis-viva equation its orbital speed rises to 33 km/s at perihelion and falls to 25.3 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 = 26 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.02 km.
Observation record and orbit quality
Astrometry from 48 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4966 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.
