Orbit and dynamics
Between its closest point (0.735 AU) and its farthest (1 AU), the heliocentric distance changes by 0.265 AU over every revolution.
One full revolution takes 0.81 yr (295 days), computed from the semi-major axis of 0.868 AU.
An eccentricity of 0.153 makes the orbit moderately elongated.
The orbital plane is tilted 12.31° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 37.3 km/s at perihelion and falls to 27.4 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 WX57, so its physical size remains unconstrained.
Observation record and orbit quality
Astrometry from 37 individual observations underpins this orbit; the fit leaves an RMS residual of 0.37 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.
