Orbit and dynamics
The path is an ellipse reaching 0.938 AU from the Sun at perihelion and 1.974 AU at aphelion, a radial span of 1.036 AU.
Applying Kepler's third law to a = 1.456 AU gives an orbital period of 1.76 yr, or about 642 days.
An eccentricity of 0.356 makes the orbit moderately elongated.
The orbital plane is tilted 13.11° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 35.8 km/s at perihelion and falls to 17 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 0.22 km, a value from direct size determination rather than from brightness alone.
A geometric albedo of 0.216 points to a comparatively bright, reflective surface.
Observation record and orbit quality
The current orbit solution is based on 165 observations and has a weighted RMS residual of 0.5978 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.
