2020 KQ

2020 KQ belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.919 AU it takes 2.66 yr to circle the Sun.

Orbit and dynamics

Between its closest point (0.787 AU) and its farthest (3.051 AU), the heliocentric distance changes by 2.264 AU over every revolution.

One full revolution takes 2.66 yr (971 days), computed from the semi-major axis of 1.919 AU.

The high eccentricity (0.59) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

A steep inclination of 26.09° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 42.3 km/s at perihelion and falls to 10.9 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 = 23.27 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.08 km.

Observation record and orbit quality

Astrometry from 58 individual observations underpins this orbit; the fit leaves an RMS residual of 0.6655 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.
