Orbit and dynamics
The path is an ellipse reaching 0.575 AU from the Sun at perihelion and 1.247 AU at aphelion, a radial span of 0.672 AU.
Applying Kepler's third law to a = 0.911 AU gives an orbital period of 0.87 yr, or about 317 days.
An eccentricity of 0.369 makes the orbit moderately elongated.
The orbital plane is tilted 6.08° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 46 km/s at perihelion and falls to 21.2 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 = 26.19 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 18 observations and has a weighted RMS residual of 0.5399 arcseconds.
Condition code U = 7 signals a poorly constrained orbit, so its future path should be treated as provisional.
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.
