Orbit and dynamics
Between its closest point (0.7 AU) and its farthest (1.369 AU), the heliocentric distance changes by 0.669 AU over every revolution.
One full revolution takes 1.05 yr (384 days), computed from the semi-major axis of 1.034 AU.
An eccentricity of 0.324 makes the orbit moderately elongated.
The orbital plane is tilted 9.22° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 40.9 km/s at perihelion and falls to 20.9 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 = 25.85 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.02 km.
Observation record and orbit quality
Astrometry from 28 individual observations underpins this orbit; the fit leaves an RMS residual of 0.5104 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.
