Orbit and dynamics
Between its closest point (0.661 AU) and its farthest (1.08 AU), the heliocentric distance changes by 0.419 AU over every revolution.
One full revolution takes 0.81 yr (297 days), computed from the semi-major axis of 0.87 AU.
An eccentricity of 0.24 makes the orbit moderately elongated.
The orbital plane is tilted 10.14° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 40.8 km/s at perihelion and falls to 25 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 = 26.1 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.02 km.
Observation record and orbit quality
Astrometry from 20 individual observations underpins this orbit; the fit leaves an RMS residual of 0.403 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.
