Orbit and dynamics
Between its closest point (0.666 AU) and its farthest (1.42 AU), the heliocentric distance changes by 0.754 AU over every revolution.
One full revolution takes 1.07 yr (389 days), computed from the semi-major axis of 1.043 AU.
An eccentricity of 0.361 makes the orbit moderately elongated.
The orbital plane is tilted 16.42° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 42.6 km/s at perihelion and falls to 20 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 0.53 km, a value from direct size determination rather than from brightness alone.
Its geometric albedo of 0.09 indicates a very dark, carbonaceous-type surface.
Observation record and orbit quality
Astrometry from 834 individual observations underpins this orbit; the fit leaves an RMS residual of 0.3886 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.
