Orbit and dynamics
The path is an ellipse reaching 0.967 AU from the Sun at perihelion and 1.75 AU at aphelion, a radial span of 0.783 AU.
Applying Kepler's third law to a = 1.359 AU gives an orbital period of 1.58 yr, or about 579 days.
An eccentricity of 0.288 makes the orbit moderately elongated.
The orbital plane is tilted 5.5° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 34.4 km/s at perihelion and falls to 19 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
The measured diameter is 0.06 km, a value from direct size determination rather than from brightness alone.
A geometric albedo of 0.126 points to a comparatively bright, reflective surface.
Observation record and orbit quality
The current orbit solution is based on 107 observations and has a weighted RMS residual of 0.3264 arcseconds.
Condition code U = 6 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.
