Orbit and dynamics
Between its closest point (0.977 AU) and its farthest (1.103 AU), the heliocentric distance changes by 0.126 AU over every revolution.
One full revolution takes 1.06 yr (387 days), computed from the semi-major axis of 1.04 AU.
With e = 0.06, the orbit is close to circular.
Its inclination of 1.65° keeps it close to the plane of the ecliptic.
By the vis-viva equation its orbital speed rises to 31 km/s at perihelion and falls to 27.5 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 2018 WV1, so its physical size remains unconstrained.
Observation record and orbit quality
Astrometry from 90 individual observations underpins this orbit; the fit leaves an RMS residual of 0.3769 arcseconds.
Condition code U = 2 means the orbit is very well determined, leaving only a small uncertainty in the future ephemeris.
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.
