Orbit and dynamics
The path is an ellipse reaching 0.957 AU from the Sun at perihelion and 1.645 AU at aphelion, a radial span of 0.688 AU.
Applying Kepler's third law to a = 1.301 AU gives an orbital period of 1.48 yr, or about 542 days.
An eccentricity of 0.264 makes the orbit moderately elongated.
The orbital plane is tilted 18.62° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 34.2 km/s at perihelion and falls to 19.9 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
No direct size measurement is available; from an absolute magnitude of H = 21.79 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.16 km.
Observation record and orbit quality
The current orbit solution is based on 156 observations and has a weighted RMS residual of 0.3906 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.
