Orbit and dynamics
The path is an ellipse reaching 0.532 AU from the Sun at perihelion and 1.028 AU at aphelion, a radial span of 0.496 AU.
Applying Kepler's third law to a = 0.78 AU gives an orbital period of 0.69 yr, or about 252 days.
An eccentricity of 0.318 makes the orbit moderately elongated.
The orbital plane is tilted 9.12° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 46.9 km/s at perihelion and falls to 24.3 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 0.02 km, a value from direct size determination rather than from brightness alone.
A geometric albedo of 0.548 points to a comparatively bright, reflective surface.
Observation record and orbit quality
The current orbit solution is based on 42 observations and has a weighted RMS residual of 0.5304 arcseconds.
Condition code U = 8 signals a poorly constrained orbit, so its future path should be treated as provisional.
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.
