Orbit and dynamics
The path is an ellipse reaching 0.966 AU from the Sun at perihelion and 1.428 AU at aphelion, a radial span of 0.462 AU.
Applying Kepler's third law to a = 1.197 AU gives an orbital period of 1.31 yr, or about 478 days.
An eccentricity of 0.193 makes the orbit moderately elongated.
The orbital plane is tilted 12° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 33.1 km/s at perihelion and falls to 22.4 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 0.45 km, a value from direct size determination rather than from brightness alone.
A geometric albedo of 0.115 points to a comparatively bright, reflective surface.
Observation record and orbit quality
The current orbit solution is based on 427 observations and has a weighted RMS residual of 0.4175 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.
