Orbit and dynamics
Between its closest point (0.785 AU) and its farthest (1.135 AU), the heliocentric distance changes by 0.35 AU over every revolution.
One full revolution takes 0.94 yr (344 days), computed from the semi-major axis of 0.96 AU.
An eccentricity of 0.183 makes the orbit moderately elongated.
The orbital plane is tilted 6.86° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 36.6 km/s at perihelion and falls to 25.3 km/s at aphelion.
Because q < 1 AU and Q > 1 AU, this orbit geometrically intersects the region of Earth's orbit.
Size and surface
No direct size measurement is available; from an absolute magnitude of H = 25 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.04 km.
Observation record and orbit quality
Astrometry from 85 individual observations underpins this orbit; the fit leaves an RMS residual of 0.408 arcseconds.
Condition code U = 3 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.
