2023 LF

2023 LF is an Amor-type near-Earth asteroid that approaches Earth from beyond our orbit without crossing it, orbiting the Sun at 2.185 AU once every 3.23 yr.

Orbit and dynamics

Between its closest point (1.038 AU) and its farthest (3.332 AU), the heliocentric distance changes by 2.294 AU over every revolution.

One full revolution takes 3.23 yr (1,180 days), computed from the semi-major axis of 2.185 AU.

The high eccentricity (0.525) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

The orbital plane is tilted 18.54° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 36.1 km/s at perihelion and falls to 11.2 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 = 20.28 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.31 km.

Observation record and orbit quality

Astrometry from 109 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4937 arcseconds.

Condition code U = 3 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.
