2024 WN

2024 WN belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.578 AU it takes 1.98 yr to circle the Sun.

Orbit and dynamics

The path is an ellipse reaching 1.006 AU from the Sun at perihelion and 2.149 AU at aphelion, a radial span of 1.143 AU.

Applying Kepler's third law to a = 1.578 AU gives an orbital period of 1.98 yr, or about 724 days.

An eccentricity of 0.362 makes the orbit moderately elongated.

The orbital plane is tilted 12.1° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 34.7 km/s at perihelion and falls to 16.2 km/s at aphelion.

Size and surface

No direct size measurement is available; from an absolute magnitude of H = 22.27 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.12 km.

Observation record and orbit quality

The current orbit solution is based on 50 observations and has a weighted RMS residual of 0.4174 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.
