Orbit and dynamics
The path is an ellipse reaching 1.142 AU from the Sun at perihelion and 1.453 AU at aphelion, a radial span of 0.311 AU.
Applying Kepler's third law to a = 1.297 AU gives an orbital period of 1.48 yr, or about 540 days.
An eccentricity of 0.12 makes the orbit moderately elongated.
The orbital plane is tilted 12.2° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 29.5 km/s at perihelion and falls to 23.2 km/s at aphelion.
Its perihelion lies just outside Earth's orbit, which is why it is classed as Earth-approaching rather than Earth-crossing.
Size and surface
No direct size measurement is available; from an absolute magnitude of H = 24.01 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.06 km.
Observation record and orbit quality
The current orbit solution is based on 37 observations and has a weighted RMS residual of 0.5656 arcseconds.
Condition code U = 6 indicates a moderately constrained orbit; predictions decades ahead still carry noticeable uncertainty.
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.
