2024 DX

2024 DX belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.165 AU it takes 1.26 yr to circle the Sun.

Orbit and dynamics

Between its closest point (0.77 AU) and its farthest (1.559 AU), the heliocentric distance changes by 0.789 AU over every revolution.

One full revolution takes 1.26 yr (459 days), computed from the semi-major axis of 1.165 AU.

An eccentricity of 0.339 makes the orbit moderately elongated.

Its inclination of 1.03° keeps it close to the plane of the ecliptic.

By the vis-viva equation its orbital speed rises to 39.3 km/s at perihelion and falls to 19.4 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 = 27.29 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.01 km.

Observation record and orbit quality

Astrometry from 56 individual observations underpins this orbit; the fit leaves an RMS residual of 0.6398 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.
