Orbit and dynamics
Between its closest point (0.994 AU) and its farthest (2.008 AU), the heliocentric distance changes by 1.014 AU over every revolution.
One full revolution takes 1.84 yr (672 days), computed from the semi-major axis of 1.501 AU.
An eccentricity of 0.338 makes the orbit moderately elongated.
A steep inclination of 22.98° carries it well above and below the ecliptic plane.
By the vis-viva equation its orbital speed rises to 34.6 km/s at perihelion and falls to 17.1 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
No direct size measurement is available; from an absolute magnitude of H = 20.74 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.25 km.
Observation record and orbit quality
Astrometry from 80 individual observations underpins this orbit; the fit leaves an RMS residual of 0.5133 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.
