Orbit and dynamics
The path is an ellipse reaching 0.909 AU from the Sun at perihelion and 1.214 AU at aphelion, a radial span of 0.305 AU.
Applying Kepler's third law to a = 1.062 AU gives an orbital period of 1.09 yr, or about 400 days.
An eccentricity of 0.143 makes the orbit moderately elongated.
Its inclination of 3.17° keeps it close to the plane of the ecliptic.
By the vis-viva equation its orbital speed rises to 33.4 km/s at perihelion and falls to 25 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 = 27 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.01 km.
Observation record and orbit quality
The current orbit solution is based on 9 observations and has a weighted RMS residual of 0.661 arcseconds.
Condition code U = 8 signals a poorly constrained orbit, so its future path should be treated as provisional.
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.
