2025 AL3

2025 AL3 is an Amor-type near-Earth asteroid that approaches Earth from beyond our orbit without crossing it, orbiting the Sun at 2.046 AU once every 2.93 yr.

Orbit and dynamics

Between its closest point (1.188 AU) and its farthest (2.904 AU), the heliocentric distance changes by 1.716 AU over every revolution.

One full revolution takes 2.93 yr (1,069 days), computed from the semi-major axis of 2.046 AU.

The high eccentricity (0.419) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

A steep inclination of 41.55° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 32.6 km/s at perihelion and falls to 13.3 km/s at aphelion.

Its perihelion lies just outside Earth's orbit, which is why it is classed as Earth-approaching rather than Earth-crossing.

Size and surface

No direct size measurement is available; from an absolute magnitude of H = 20.55 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.28 km.

Observation record and orbit quality

Astrometry from 23 individual observations underpins this orbit; the fit leaves an RMS residual of 0.2908 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.
