Orbit and dynamics
Between its closest point (1.097 AU) and its farthest (1.259 AU), the heliocentric distance changes by 0.162 AU over every revolution.
One full revolution takes 1.28 yr (467 days), computed from the semi-major axis of 1.178 AU.
With e = 0.069, the orbit is close to circular.
A steep inclination of 35.39° carries it well above and below the ecliptic plane.
By the vis-viva equation its orbital speed rises to 29.4 km/s at perihelion and falls to 25.6 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 = 20.29 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.31 km.
Observation record and orbit quality
Astrometry from 211 individual observations underpins this orbit; the fit leaves an RMS residual of 0.5089 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.
