Orbit and dynamics
Between its closest point (1.079 AU) and its farthest (1.268 AU), the heliocentric distance changes by 0.189 AU over every revolution.
One full revolution takes 1.27 yr (464 days), computed from the semi-major axis of 1.173 AU.
With e = 0.081, the orbit is close to circular.
Its inclination of 3.07° keeps it close to the plane of the ecliptic.
By the vis-viva equation its orbital speed rises to 29.8 km/s at perihelion and falls to 25.4 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 = 24.54 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.04 km.
Observation record and orbit quality
Astrometry from 84 individual observations underpins this orbit; the fit leaves an RMS residual of 0.5918 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.
