Orbit and dynamics
Between its closest point (1.033 AU) and its farthest (1.765 AU), the heliocentric distance changes by 0.732 AU over every revolution.
One full revolution takes 1.65 yr (604 days), computed from the semi-major axis of 1.399 AU.
An eccentricity of 0.262 makes the orbit moderately elongated.
Its inclination of 4.87° keeps it close to the plane of the ecliptic.
By the vis-viva equation its orbital speed rises to 32.9 km/s at perihelion and falls to 19.3 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 93 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4862 arcseconds.
Condition code U = 4 indicates a moderately constrained orbit; predictions decades ahead still carry noticeable uncertainty.
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.
