Orbit and dynamics
Between its closest point (0.722 AU) and its farthest (1.436 AU), the heliocentric distance changes by 0.714 AU over every revolution.
One full revolution takes 1.12 yr (409 days), computed from the semi-major axis of 1.079 AU.
An eccentricity of 0.331 makes the orbit moderately elongated.
The orbital plane is tilted 11.51° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 40.4 km/s at perihelion and falls to 20.3 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 = 23 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.09 km.
Observation record and orbit quality
Astrometry from 73 individual observations underpins this orbit; the fit leaves an RMS residual of 0.5168 arcseconds.
Condition code U = 6 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.
