2022 CK7

2022 CK7 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.244 AU it takes 1.39 yr to circle the Sun.

Orbit and dynamics

Between its closest point (0.836 AU) and its farthest (1.651 AU), the heliocentric distance changes by 0.815 AU over every revolution.

One full revolution takes 1.39 yr (507 days), computed from the semi-major axis of 1.244 AU.

An eccentricity of 0.328 makes the orbit moderately elongated.

Its inclination of 2.04° keeps it close to the plane of the ecliptic.

By the vis-viva equation its orbital speed rises to 37.5 km/s at perihelion and falls to 19 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 = 24.78 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.04 km.

Observation record and orbit quality

Astrometry from 41 individual observations underpins this orbit; the fit leaves an RMS residual of 0.5163 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.
