2023 CD1

2023 CD1 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.066 AU it takes 1.10 yr to circle the Sun.

Orbit and dynamics

Between its closest point (0.552 AU) and its farthest (1.58 AU), the heliocentric distance changes by 1.028 AU over every revolution.

One full revolution takes 1.10 yr (402 days), computed from the semi-major axis of 1.066 AU.

The high eccentricity (0.482) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

The orbital plane is tilted 9.9° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 48.8 km/s at perihelion and falls to 17 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 = 23.75 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.06 km.

Observation record and orbit quality

Astrometry from 34 individual observations underpins this orbit; the fit leaves an RMS residual of 0.3987 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.
