Orbit and dynamics
Between its closest point (0.82 AU) and its farthest (1.158 AU), the heliocentric distance changes by 0.338 AU over every revolution.
One full revolution takes 0.98 yr (359 days), computed from the semi-major axis of 0.989 AU.
An eccentricity of 0.171 makes the orbit moderately elongated.
A steep inclination of 21.49° carries it well above and below the ecliptic plane.
By the vis-viva equation its orbital speed rises to 35.6 km/s at perihelion and falls to 25.2 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
The measured diameter is 0.21 km, a value from direct size determination rather than from brightness alone.
Its geometric albedo of 0.075 indicates a very dark, carbonaceous-type surface.
Observation record and orbit quality
Astrometry from 95 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4553 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.
