2016 WE58

2016 WE58 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.597 AU it takes 2.02 yr to circle the Sun.

Orbit and dynamics

Between its closest point (0.903 AU) and its farthest (2.292 AU), the heliocentric distance changes by 1.389 AU over every revolution.

One full revolution takes 2.02 yr (737 days), computed from the semi-major axis of 1.597 AU.

The high eccentricity (0.435) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

Its inclination of 1.14° keeps it close to the plane of the ecliptic.

By the vis-viva equation its orbital speed rises to 37.5 km/s at perihelion and falls to 14.8 km/s at aphelion.

Because q < 1 AU and Q > 1 AU, this orbit geometrically intersects the region of Earth's orbit.

Size and surface

Neither a measured diameter nor a reliable absolute magnitude is available for 2016 WE58, so its physical size remains unconstrained.

Observation record and orbit quality

Astrometry from 29 individual observations underpins this orbit; the fit leaves an RMS residual of 0.57 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.
