Fuls

Fuls follows a distinctly cometary orbit: an eccentricity of 0.994 carries it from 1.709 AU at perihelion out to 604.3 AU at aphelion.

Orbit and dynamics

Between its closest point (1.709 AU) and its farthest (604.3 AU), the heliocentric distance changes by 602.6 AU over every revolution.

One full revolution takes 5,274 yr (1,926,434 days), computed from the semi-major axis of 303.0 AU.

The high eccentricity (0.994) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

The orbital plane is tilted 11.68° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 32.2 km/s at perihelion and falls to 0.1 km/s at aphelion.

Its Tisserand parameter with respect to Jupiter is T_J = 1.6, a standard discriminator between asteroidal and cometary dynamics.

Size and surface

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

Observation record and orbit quality

Astrometry from 114 individual observations underpins this orbit; the fit leaves an RMS residual of 0.5724 arcseconds.

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.
