Orbit and dynamics
Between its closest point (0.76 AU) and its farthest (1.317 AU), the heliocentric distance changes by 0.557 AU over every revolution.
One full revolution takes 1.06 yr (386 days), computed from the semi-major axis of 1.038 AU.
An eccentricity of 0.268 makes the orbit moderately elongated.
The orbital plane is tilted 18.9° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 38.5 km/s at perihelion and falls to 22.2 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 = 25.2 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.03 km.
Observation record and orbit quality
Astrometry from 80 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4841 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.
