2017 FC228

2017 FC228 is an Amor-type near-Earth asteroid that approaches Earth from beyond our orbit without crossing it, orbiting the Sun at 1.726 AU once every 2.27 yr.

Orbit and dynamics

Between its closest point (1.155 AU) and its farthest (2.297 AU), the heliocentric distance changes by 1.142 AU over every revolution.

One full revolution takes 2.27 yr (828 days), computed from the semi-major axis of 1.726 AU.

An eccentricity of 0.331 makes the orbit moderately elongated.

The orbital plane is tilted 6.27° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 32 km/s at perihelion and falls to 16.1 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 = 24.74 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.04 km.

Observation record and orbit quality

Astrometry from 18 individual observations underpins this orbit; the fit leaves an RMS residual of 0.1208 arcseconds.

Condition code U = 9 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.
