Orbit and dynamics
Between its closest point (1.261 AU) and its farthest (1.734 AU), the heliocentric distance changes by 0.473 AU over every revolution.
One full revolution takes 1.83 yr (669 days), computed from the semi-major axis of 1.497 AU.
An eccentricity of 0.158 makes the orbit moderately elongated.
A steep inclination of 22.34° carries it well above and below the ecliptic plane.
By the vis-viva equation its orbital speed rises to 28.5 km/s at perihelion and falls to 20.8 km/s at aphelion.
Its perihelion lies just outside Earth's orbit, which is why it is classed as Earth-approaching rather than Earth-crossing.
Size and surface
No direct size measurement is available; from an absolute magnitude of H = 21.53 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.18 km.
Observation record and orbit quality
Astrometry from 27 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4718 arcseconds.
Condition code U = 5 indicates a moderately constrained orbit; predictions decades ahead still carry noticeable uncertainty.
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.
