Orbit and dynamics
The path is an ellipse reaching 0.965 AU from the Sun at perihelion and 1.301 AU at aphelion, a radial span of 0.336 AU.
Applying Kepler's third law to a = 1.133 AU gives an orbital period of 1.21 yr, or about 440 days.
An eccentricity of 0.148 makes the orbit moderately elongated.
A steep inclination of 25.92° carries it well above and below the ecliptic plane.
By the vis-viva equation its orbital speed rises to 32.5 km/s at perihelion and falls to 24.1 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
The measured diameter is 0.2 km, a value from direct size determination rather than from brightness alone.
Its geometric albedo of 0.037 indicates a very dark, carbonaceous-type surface.
Observation record and orbit quality
The current orbit solution is based on 96 observations and has a weighted RMS residual of 0.5219 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.
