Orbit and dynamics
Between its closest point (0.843 AU) and its farthest (1.127 AU), the heliocentric distance changes by 0.284 AU over every revolution.
One full revolution takes 0.98 yr (357 days), computed from the semi-major axis of 0.985 AU.
An eccentricity of 0.144 makes the orbit moderately elongated.
A steep inclination of 20.99° carries it well above and below the ecliptic plane.
By the vis-viva equation its orbital speed rises to 34.7 km/s at perihelion and falls to 25.9 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 = 22.1 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.14 km.
Observation record and orbit quality
Astrometry from 142 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4885 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.
