Orbit and dynamics
The path is an ellipse reaching 0.772 AU from the Sun at perihelion and 1.148 AU at aphelion, a radial span of 0.376 AU.
Applying Kepler's third law to a = 0.96 AU gives an orbital period of 0.94 yr, or about 343 days.
An eccentricity of 0.196 makes the orbit moderately elongated.
Its inclination of 2.19° keeps it close to the plane of the ecliptic.
By the vis-viva equation its orbital speed rises to 37.1 km/s at perihelion and falls to 24.9 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 0.03 km, a value from direct size determination rather than from brightness alone.
A geometric albedo of 0.482 points to a comparatively bright, reflective surface.
Observation record and orbit quality
The current orbit solution is based on 73 observations and has a weighted RMS residual of 0.433 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.
