2023 DX

2023 DX belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.632 AU it takes 2.08 yr to circle the Sun.

Orbit and dynamics

The path is an ellipse reaching 0.817 AU from the Sun at perihelion and 2.447 AU at aphelion, a radial span of 1.63 AU.

Applying Kepler's third law to a = 1.632 AU gives an orbital period of 2.08 yr, or about 762 days.

The high eccentricity (0.499) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

Its inclination of 0.69° keeps it close to the plane of the ecliptic.

By the vis-viva equation its orbital speed rises to 40.3 km/s at perihelion and falls to 13.5 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 = 25.91 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.02 km.

Observation record and orbit quality

The current orbit solution is based on 30 observations and has a weighted RMS residual of 0.4012 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.
