Orbit and dynamics
The path is an ellipse reaching 0.706 AU from the Sun at perihelion and 1.241 AU at aphelion, a radial span of 0.535 AU.
Applying Kepler's third law to a = 0.974 AU gives an orbital period of 0.96 yr, or about 351 days.
An eccentricity of 0.274 makes the orbit moderately elongated.
The orbital plane is tilted 5.71° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 40 km/s at perihelion and falls to 22.8 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 = 22.14 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.13 km.
Observation record and orbit quality
The current orbit solution is based on 376 observations and has a weighted RMS residual of 0.2888 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.
