Orbit and dynamics
The path is an ellipse reaching 0.769 AU from the Sun at perihelion and 1.066 AU at aphelion, a radial span of 0.297 AU.
Applying Kepler's third law to a = 0.917 AU gives an orbital period of 0.88 yr, or about 321 days.
An eccentricity of 0.162 makes the orbit moderately elongated.
The orbital plane is tilted 13.06° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 36.6 km/s at perihelion and falls to 26.4 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 0.17 km, a value from direct size determination rather than from brightness alone.
Its geometric albedo of 0.048 indicates a very dark, carbonaceous-type surface.
Observation record and orbit quality
The current orbit solution is based on 23 observations and has a weighted RMS residual of 0.4464 arcseconds.
Condition code U = 2 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.
