Orbit and dynamics
The path is an ellipse reaching 0.81 AU from the Sun at perihelion and 1.11 AU at aphelion, a radial span of 0.3 AU.
Applying Kepler's third law to a = 0.96 AU gives an orbital period of 0.94 yr, or about 344 days.
An eccentricity of 0.156 makes the orbit moderately elongated.
The orbital plane is tilted 7.15° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 35.6 km/s at perihelion and falls to 26 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 = 26.1 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.02 km.
Observation record and orbit quality
The current orbit solution is based on 65 observations and has a weighted RMS residual of 0.435 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.
