Orbit and dynamics
Between its closest point (0.743 AU) and its farthest (1.145 AU), the heliocentric distance changes by 0.402 AU over every revolution.
One full revolution takes 0.92 yr (335 days), computed from the semi-major axis of 0.944 AU.
An eccentricity of 0.213 makes the orbit moderately elongated.
Its inclination of 0.26° keeps it close to the plane of the ecliptic.
By the vis-viva equation its orbital speed rises to 38.1 km/s at perihelion and falls to 24.7 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 KQ, so its physical size remains unconstrained.
Observation record and orbit quality
Astrometry from 35 individual observations underpins this orbit; the fit leaves an RMS residual of 0.449 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.
