Orbit and dynamics
The path is an ellipse reaching 0.772 AU from the Sun at perihelion and 1.384 AU at aphelion, a radial span of 0.612 AU.
Applying Kepler's third law to a = 1.078 AU gives an orbital period of 1.12 yr, or about 409 days.
An eccentricity of 0.283 makes the orbit moderately elongated.
The orbital plane is tilted 14.13° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 38.4 km/s at perihelion and falls to 21.4 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 = 20.84 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.24 km.
Observation record and orbit quality
The current orbit solution is based on 285 observations and has a weighted RMS residual of 0.4352 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.
