2015 FO34

2015 FO34 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.49 AU it takes 1.82 yr to circle the Sun.

Orbit and dynamics

The path is an ellipse reaching 1.007 AU from the Sun at perihelion and 1.973 AU at aphelion, a radial span of 0.966 AU.

Applying Kepler's third law to a = 1.49 AU gives an orbital period of 1.82 yr, or about 664 days.

An eccentricity of 0.324 makes the orbit moderately elongated.

Its inclination of 3.44° keeps it close to the plane of the ecliptic.

By the vis-viva equation its orbital speed rises to 34.2 km/s at perihelion and falls to 17.4 km/s at aphelion.

Size and surface

No direct size measurement is available; from an absolute magnitude of H = 27.6 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.01 km.

Observation record and orbit quality

The current orbit solution is based on 29 observations and has a weighted RMS residual of 0.5574 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.
