Orbit and dynamics
Between its closest point (1.056 AU) and its farthest (1.554 AU), the heliocentric distance changes by 0.498 AU over every revolution.
One full revolution takes 1.49 yr (545 days), computed from the semi-major axis of 1.305 AU.
An eccentricity of 0.191 makes the orbit moderately elongated.
Its inclination of 2.83° keeps it close to the plane of the ecliptic.
By the vis-viva equation its orbital speed rises to 31.6 km/s at perihelion and falls to 21.5 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 = 24.9 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.04 km.
Observation record and orbit quality
Astrometry from 163 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4858 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.
