Orbit and dynamics
Between its closest point (1.012 AU) and its farthest (1.472 AU), the heliocentric distance changes by 0.46 AU over every revolution.
One full revolution takes 1.38 yr (506 days), computed from the semi-major axis of 1.242 AU.
An eccentricity of 0.185 makes the orbit moderately elongated.
The orbital plane is tilted 13.18° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 32.2 km/s at perihelion and falls to 22.2 km/s at aphelion.
Size and surface
No direct size measurement is available; from an absolute magnitude of H = 26.8 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.02 km.
Observation record and orbit quality
Astrometry from 36 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4074 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.
