NEOWISE

NEOWISE follows a distinctly cometary orbit: an eccentricity of 0.934 carries it from 1.585 AU at perihelion out to 46.295 AU at aphelion.

Orbit and dynamics

Between its closest point (1.585 AU) and its farthest (46.295 AU), the heliocentric distance changes by 44.71 AU over every revolution.

One full revolution takes 117 yr (42,784 days), computed from the semi-major axis of 23.94 AU.

The high eccentricity (0.934) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

A steep inclination of 97.29° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 32.9 km/s at perihelion and falls to 1.1 km/s at aphelion.

Its Tisserand parameter with respect to Jupiter is T_J = 0.02, a standard discriminator between asteroidal and cometary dynamics.

Size and surface

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

Observation record and orbit quality

Astrometry from 108 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4687 arcseconds.

Condition code U = 5 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.
