Orbit and dynamics
The path is an ellipse reaching 0.934 AU from the Sun at perihelion and 1.27 AU at aphelion, a radial span of 0.336 AU.
Applying Kepler's third law to a = 1.102 AU gives an orbital period of 1.16 yr, or about 423 days.
An eccentricity of 0.153 makes the orbit moderately elongated.
A steep inclination of 27.95° carries it well above and below the ecliptic plane.
By the vis-viva equation its orbital speed rises to 33.1 km/s at perihelion and falls to 24.3 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 = 21.76 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.16 km.
Observation record and orbit quality
The current orbit solution is based on 118 observations and has a weighted RMS residual of 0.4693 arcseconds.
Condition code U = 3 indicates a moderately constrained orbit; predictions decades ahead still carry noticeable uncertainty.
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.
