Orbit and dynamics
The path is an ellipse reaching 0.958 AU from the Sun at perihelion and 1.169 AU at aphelion, a radial span of 0.211 AU.
Applying Kepler's third law to a = 1.064 AU gives an orbital period of 1.10 yr, or about 401 days.
With e = 0.099, the orbit is close to circular.
The orbital plane is tilted 9.32° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 31.9 km/s at perihelion and falls to 26.1 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 = 24.98 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.04 km.
Observation record and orbit quality
The current orbit solution is based on 68 observations and has a weighted RMS residual of 0.4804 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.
