Orbit and dynamics
Between its closest point (0.708 AU) and its farthest (1.01 AU), the heliocentric distance changes by 0.302 AU over every revolution.
One full revolution takes 0.80 yr (291 days), computed from the semi-major axis of 0.859 AU.
An eccentricity of 0.175 makes the orbit moderately elongated.
The orbital plane is tilted 5.69° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 38.4 km/s at perihelion and falls to 26.9 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 = 29.1 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.01 km.
Observation record and orbit quality
Astrometry from 23 individual observations underpins this orbit; the fit leaves an RMS residual of 0.7353 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.
