Orbit and dynamics
The path is an ellipse reaching 0.747 AU from the Sun at perihelion and 1.03 AU at aphelion, a radial span of 0.283 AU.
Applying Kepler's third law to a = 0.889 AU gives an orbital period of 0.84 yr, or about 306 days.
An eccentricity of 0.159 makes the orbit moderately elongated.
Its inclination of 2.73° 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 26.9 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 0.07 km, a value from direct size determination rather than from brightness alone.
Its geometric albedo of 0.015 indicates a very dark, carbonaceous-type surface.
Observation record and orbit quality
The current orbit solution is based on 78 observations and has a weighted RMS residual of 0.6103 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.
