Orbit and dynamics
The path is an ellipse reaching 1.025 AU from the Sun at perihelion and 2.259 AU at aphelion, a radial span of 1.234 AU.
Applying Kepler's third law to a = 1.642 AU gives an orbital period of 2.10 yr, or about 769 days.
An eccentricity of 0.376 makes the orbit moderately elongated.
The orbital plane is tilted 11.05° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 34.5 km/s at perihelion and falls to 15.7 km/s at aphelion.
Its perihelion lies just outside Earth's orbit, which is why it is classed as Earth-approaching rather than Earth-crossing.
Size and surface
The measured diameter is 0.35 km, a value from direct size determination rather than from brightness alone.
Its geometric albedo of 0.023 indicates a very dark, carbonaceous-type surface.
Observation record and orbit quality
The current orbit solution is based on 55 observations and has a weighted RMS residual of 0.3658 arcseconds.
Condition code U = 1 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.
