2023 KD2

2023 KD2 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.045 AU it takes 1.07 yr to circle the Sun.

Orbit and dynamics

Between its closest point (0.794 AU) and its farthest (1.296 AU), the heliocentric distance changes by 0.502 AU over every revolution.

One full revolution takes 1.07 yr (390 days), computed from the semi-major axis of 1.045 AU.

An eccentricity of 0.24 makes the orbit moderately elongated.

The orbital plane is tilted 13.44° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 37.2 km/s at perihelion and falls to 22.8 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 = 24.9 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.04 km.

Observation record and orbit quality

Astrometry from 63 individual observations underpins this orbit; the fit leaves an RMS residual of 0.5503 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.
