2024 JM

2024 JM belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.092 AU it takes 1.14 yr to circle the Sun.

Orbit and dynamics

The path is an ellipse reaching 0.685 AU from the Sun at perihelion and 1.499 AU at aphelion, a radial span of 0.814 AU.

Applying Kepler's third law to a = 1.092 AU gives an orbital period of 1.14 yr, or about 417 days.

An eccentricity of 0.373 makes the orbit moderately elongated.

The orbital plane is tilted 18.4° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 42.2 km/s at perihelion and falls to 19.3 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 = 24.5 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.04 km.

Observation record and orbit quality

The current orbit solution is based on 28 observations and has a weighted RMS residual of 0.2889 arcseconds.

Condition code U = 8 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.
