Orbit and dynamics
The path is an ellipse reaching 0.999 AU from the Sun at perihelion and 1.201 AU at aphelion, a radial span of 0.202 AU.
Applying Kepler's third law to a = 1.1 AU gives an orbital period of 1.15 yr, or about 421 days.
With e = 0.091, the orbit is close to circular.
A steep inclination of 21.38° carries it well above and below the ecliptic plane.
By the vis-viva equation its orbital speed rises to 31.1 km/s at perihelion and falls to 25.9 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 = 24.3 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.05 km.
Observation record and orbit quality
The current orbit solution is based on 72 observations and has a weighted RMS residual of 0.3166 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.
