Orbit and dynamics
Between its closest point (1.103 AU) and its farthest (1.186 AU), the heliocentric distance changes by 0.083 AU over every revolution.
One full revolution takes 1.23 yr (448 days), computed from the semi-major axis of 1.145 AU.
With e = 0.036, the orbit is close to circular.
Its inclination of 2.4° keeps it close to the plane of the ecliptic.
By the vis-viva equation its orbital speed rises to 28.9 km/s at perihelion and falls to 26.9 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 = 24.44 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.05 km.
Observation record and orbit quality
Astrometry from 82 individual observations underpins this orbit; the fit leaves an RMS residual of 0.5745 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.
