2014 WW4

2014 WW4 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.094 AU it takes 1.14 yr to circle the Sun.

Orbit and dynamics

The path is an ellipse reaching 1.01 AU from the Sun at perihelion and 1.178 AU at aphelion, a radial span of 0.168 AU.

Applying Kepler's third law to a = 1.094 AU gives an orbital period of 1.14 yr, or about 418 days.

With e = 0.077, the orbit is close to circular.

A steep inclination of 26.97° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 30.8 km/s at perihelion and falls to 26.4 km/s at aphelion.

Size and surface

No direct size measurement is available; from an absolute magnitude of H = 25.3 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.03 km.

Observation record and orbit quality

The current orbit solution is based on 33 observations and has a weighted RMS residual of 0.7373 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.
