2012 FA14

2012 FA14 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.414 AU it takes 1.68 yr to circle the Sun.

Orbit and dynamics

The path is an ellipse reaching 1.013 AU from the Sun at perihelion and 1.815 AU at aphelion, a radial span of 0.802 AU.

Applying Kepler's third law to a = 1.414 AU gives an orbital period of 1.68 yr, or about 614 days.

An eccentricity of 0.283 makes the orbit moderately elongated.

Its inclination of 3.29° keeps it close to the plane of the ecliptic.

By the vis-viva equation its orbital speed rises to 33.5 km/s at perihelion and falls to 18.7 km/s at aphelion.

Size and surface

No direct size measurement is available; from an absolute magnitude of H = 23.1 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.09 km.

Observation record and orbit quality

The current orbit solution is based on 94 observations and has a weighted RMS residual of 0.3834 arcseconds.

Condition code U = 0 means the orbit is very well determined, leaving only a small uncertainty in the future ephemeris.

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.
