Orbit and dynamics
The path is an ellipse reaching 0.773 AU from the Sun at perihelion and 1.263 AU at aphelion, a radial span of 0.49 AU.
Applying Kepler's third law to a = 1.018 AU gives an orbital period of 1.03 yr, or about 375 days.
An eccentricity of 0.24 makes the orbit moderately elongated.
Its inclination of 1.53° keeps it close to the plane of the ecliptic.
By the vis-viva equation its orbital speed rises to 37.7 km/s at perihelion and falls to 23.1 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 = 26.5 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.02 km.
Observation record and orbit quality
The current orbit solution is based on 61 observations and has a weighted RMS residual of 0.2864 arcseconds.
Condition code U = 5 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.
