Orbit and dynamics
The path is an ellipse reaching 1.011 AU from the Sun at perihelion and 1.941 AU at aphelion, a radial span of 0.93 AU.
Applying Kepler's third law to a = 1.476 AU gives an orbital period of 1.79 yr, or about 655 days.
An eccentricity of 0.315 makes the orbit moderately elongated.
The orbital plane is tilted 12.61° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 34 km/s at perihelion and falls to 17.7 km/s at aphelion.
Size and surface
The measured diameter is 0.5 km, a value from direct size determination rather than from brightness alone.
A geometric albedo of 0.34 points to a comparatively bright, reflective surface.
Observation record and orbit quality
The current orbit solution is based on 963 observations and has a weighted RMS residual of 0.4938 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.
