Orbit and dynamics
The path is an ellipse reaching 0.995 AU from the Sun at perihelion and 1.234 AU at aphelion, a radial span of 0.239 AU.
Applying Kepler's third law to a = 1.114 AU gives an orbital period of 1.18 yr, or about 429 days.
An eccentricity of 0.107 makes the orbit moderately elongated.
The orbital plane is tilted 13.27° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 31.4 km/s at perihelion and falls to 25.3 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 0.25 km, a value from direct size determination rather than from brightness alone.
Its geometric albedo of 0.034 indicates a very dark, carbonaceous-type surface.
Observation record and orbit quality
The current orbit solution is based on 80 observations and has a weighted RMS residual of 0.446 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.
