Orbit and dynamics
The path is an ellipse reaching 0.97 AU from the Sun at perihelion and 1.082 AU at aphelion, a radial span of 0.112 AU.
Applying Kepler's third law to a = 1.026 AU gives an orbital period of 1.04 yr, or about 380 days.
With e = 0.055, the orbit is close to circular.
Its inclination of 2.76° keeps it close to the plane of the ecliptic.
By the vis-viva equation its orbital speed rises to 31.1 km/s at perihelion and falls to 27.8 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 = 28.99 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 49 observations and has a weighted RMS residual of 0.5865 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.
