Orbit and dynamics
Between its closest point (1.008 AU) and its farthest (1.696 AU), the heliocentric distance changes by 0.688 AU over every revolution.
One full revolution takes 1.57 yr (574 days), computed from the semi-major axis of 1.352 AU.
An eccentricity of 0.254 makes the orbit moderately elongated.
The orbital plane is tilted 9.37° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 33.2 km/s at perihelion and falls to 19.8 km/s at aphelion.
Size and surface
No direct size measurement is available; from an absolute magnitude of H = 23.83 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.06 km.
Observation record and orbit quality
Astrometry from 38 individual observations underpins this orbit; the fit leaves an RMS residual of 0.3755 arcseconds.
Condition code U = 5 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.
