Orbit and dynamics
Between its closest point (0.663 AU) and its farthest (1.164 AU), the heliocentric distance changes by 0.501 AU over every revolution.
One full revolution takes 0.87 yr (319 days), computed from the semi-major axis of 0.914 AU.
An eccentricity of 0.274 makes the orbit moderately elongated.
A steep inclination of 36.29° carries it well above and below the ecliptic plane.
By the vis-viva equation its orbital speed rises to 41.3 km/s at perihelion and falls to 23.5 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 1.07 km, a value from direct size determination rather than from brightness alone.
Its geometric albedo of 0.08 indicates a very dark, carbonaceous-type surface.
Observation record and orbit quality
Astrometry from 860 individual observations underpins this orbit; the fit leaves an RMS residual of 0.5235 arcseconds.
Condition code U = 0 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.
