2024 XS2

2024 XS2 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.15 AU it takes 1.23 yr to circle the Sun.

Orbit and dynamics

The path is an ellipse reaching 0.85 AU from the Sun at perihelion and 1.45 AU at aphelion, a radial span of 0.6 AU.

Applying Kepler's third law to a = 1.15 AU gives an orbital period of 1.23 yr, or about 450 days.

An eccentricity of 0.261 makes the orbit moderately elongated.

Its inclination of 4.46° keeps it close to the plane of the ecliptic.

By the vis-viva equation its orbital speed rises to 36.3 km/s at perihelion and falls to 21.3 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 = 29.31 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0 km.

Observation record and orbit quality

The current orbit solution is based on 20 observations and has a weighted RMS residual of 0.5987 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.
