Orbit and dynamics
Between its closest point (1.051 AU) and its farthest (1.085 AU), the heliocentric distance changes by 0.034 AU over every revolution.
One full revolution takes 1.10 yr (403 days), computed from the semi-major axis of 1.068 AU.
With e = 0.016, the orbit is close to circular.
The orbital plane is tilted 15.96° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 29.3 km/s at perihelion and falls to 28.4 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 = 25.6 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.03 km.
Observation record and orbit quality
Astrometry from 68 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4499 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.
