Orbit and dynamics
Between its closest point (0.892 AU) and its farthest (1.464 AU), the heliocentric distance changes by 0.572 AU over every revolution.
One full revolution takes 1.28 yr (467 days), computed from the semi-major axis of 1.178 AU.
An eccentricity of 0.243 makes the orbit moderately elongated.
The orbital plane is tilted 17.3° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 35.2 km/s at perihelion and falls to 21.4 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 = 22.43 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.12 km.
Observation record and orbit quality
Astrometry from 42 individual observations underpins this orbit; the fit leaves an RMS residual of 0.5932 arcseconds.
Condition code U = 1 means the orbit is very well determined, leaving only a small uncertainty in the future ephemeris.
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.
