2024 JF2

2024 JF2 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.999 AU it takes 2.83 yr to circle the Sun.

Orbit and dynamics

The path is an ellipse reaching 1.017 AU from the Sun at perihelion and 2.98 AU at aphelion, a radial span of 1.963 AU.

Applying Kepler's third law to a = 1.999 AU gives an orbital period of 2.83 yr, or about 1,032 days.

The high eccentricity (0.491) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

The orbital plane is tilted 7.89° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 36.1 km/s at perihelion and falls to 12.3 km/s at aphelion.

Size and surface

No direct size measurement is available; from an absolute magnitude of H = 22.7 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.1 km.

Observation record and orbit quality

The current orbit solution is based on 60 observations and has a weighted RMS residual of 0.499 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.
