2024 SP

2024 SP belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.349 AU it takes 1.57 yr to circle the Sun.

Orbit and dynamics

Between its closest point (1.016 AU) and its farthest (1.682 AU), the heliocentric distance changes by 0.666 AU over every revolution.

One full revolution takes 1.57 yr (572 days), computed from the semi-major axis of 1.349 AU.

An eccentricity of 0.247 makes the orbit moderately elongated.

The orbital plane is tilted 9.85° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 33 km/s at perihelion and falls to 19.9 km/s at aphelion.

Size and surface

No direct size measurement is available; from an absolute magnitude of H = 28.81 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.01 km.

Observation record and orbit quality

Astrometry from 23 individual observations underpins this orbit; the fit leaves an RMS residual of 0.6297 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.
