2023 CS

2023 CS belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 2.22 AU it takes 3.31 yr to circle the Sun.

Orbit and dynamics

Between its closest point (0.801 AU) and its farthest (3.639 AU), the heliocentric distance changes by 2.838 AU over every revolution.

One full revolution takes 3.31 yr (1,208 days), computed from the semi-major axis of 2.22 AU.

The high eccentricity (0.639) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

The orbital plane is tilted 10.84° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 42.6 km/s at perihelion and falls to 9.4 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 = 21.7 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.16 km.

Observation record and orbit quality

Astrometry from 108 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4662 arcseconds.

Condition code U = 5 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.
