2014 WQ201

2014 WQ201 is an Amor-type near-Earth asteroid that approaches Earth from beyond our orbit without crossing it, orbiting the Sun at 1.702 AU once every 2.22 yr.

Orbit and dynamics

The path is an ellipse reaching 1.078 AU from the Sun at perihelion and 2.326 AU at aphelion, a radial span of 1.248 AU.

Applying Kepler's third law to a = 1.702 AU gives an orbital period of 2.22 yr, or about 811 days.

An eccentricity of 0.366 makes the orbit moderately elongated.

The orbital plane is tilted 8.25° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 33.5 km/s at perihelion and falls to 15.5 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 = 22.52 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.11 km.

Observation record and orbit quality

The current orbit solution is based on 128 observations and has a weighted RMS residual of 0.5127 arcseconds.

Condition code U = 4 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.
