Orbit and dynamics
The path is an ellipse reaching 0.921 AU from the Sun at perihelion and 1.058 AU at aphelion, a radial span of 0.137 AU.
Applying Kepler's third law to a = 0.99 AU gives an orbital period of 0.98 yr, or about 360 days.
With e = 0.07, the orbit is close to circular.
The orbital plane is tilted 7.48° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 32.1 km/s at perihelion and falls to 27.9 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
Neither a measured diameter nor a reliable absolute magnitude is available for 2026 FJ2, so its physical size remains unconstrained.
Observation record and orbit quality
The current orbit solution is based on 26 observations and has a weighted RMS residual of 0.4326 arcseconds.
Condition code U = 4 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.
