2024 EC4

2024 EC4 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.067 AU it takes 1.10 yr to circle the Sun.

Orbit and dynamics

Between its closest point (0.965 AU) and its farthest (1.17 AU), the heliocentric distance changes by 0.205 AU over every revolution.

One full revolution takes 1.10 yr (403 days), computed from the semi-major axis of 1.067 AU.

With e = 0.096, the orbit is close to circular.

The orbital plane is tilted 6.87° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 31.7 km/s at perihelion and falls to 26.2 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 = 25.71 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.03 km.

Observation record and orbit quality

Astrometry from 27 individual observations underpins this orbit; the fit leaves an RMS residual of 0.5873 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.
