Orbit and dynamics
The path is an ellipse reaching 0.955 AU from the Sun at perihelion and 1.01 AU at aphelion, a radial span of 0.055 AU.
Applying Kepler's third law to a = 0.983 AU gives an orbital period of 0.97 yr, or about 356 days.
With e = 0.028, the orbit is close to circular.
The orbital plane is tilted 5.25° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 30.9 km/s at perihelion and falls to 29.2 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 = 24.8 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 40 observations and has a weighted RMS residual of 0.428 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.
