Orbit and dynamics
Between its closest point (0.91 AU) and its farthest (1.385 AU), the heliocentric distance changes by 0.475 AU over every revolution.
One full revolution takes 1.23 yr (449 days), computed from the semi-major axis of 1.148 AU.
An eccentricity of 0.207 makes the orbit moderately elongated.
The orbital plane is tilted 15.16° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 34.3 km/s at perihelion and falls to 22.5 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 0.38 km, a value from direct size determination rather than from brightness alone.
Its geometric albedo of 0.023 indicates a very dark, carbonaceous-type surface.
Observation record and orbit quality
Astrometry from 102 individual observations underpins this orbit; the fit leaves an RMS residual of 0.5545 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.
