Orbit and dynamics
Between its closest point (0.789 AU) and its farthest (1.579 AU), the heliocentric distance changes by 0.79 AU over every revolution.
One full revolution takes 1.29 yr (471 days), computed from the semi-major axis of 1.184 AU.
An eccentricity of 0.334 makes the orbit moderately elongated.
The orbital plane is tilted 6.41° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 38.7 km/s at perihelion and falls to 19.4 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 = 26.4 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.02 km.
Observation record and orbit quality
Astrometry from 30 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4172 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.
