Orbit and dynamics
Between its closest point (0.851 AU) and its farthest (1.879 AU), the heliocentric distance changes by 1.028 AU over every revolution.
One full revolution takes 1.59 yr (582 days), computed from the semi-major axis of 1.365 AU.
An eccentricity of 0.377 makes the orbit moderately elongated.
The orbital plane is tilted 8.67° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 37.9 km/s at perihelion and falls to 17.2 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 0.86 km, a value from direct size determination rather than from brightness alone.
A geometric albedo of 0.137 points to a comparatively bright, reflective surface.
Observation record and orbit quality
Astrometry from 2,094 individual observations underpins this orbit; the fit leaves an RMS residual of 0.3935 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.
