Ferris

Ferris follows a distinctly cometary orbit: an eccentricity of 0.954 carries it from 2.543 AU at perihelion out to 108.6 AU at aphelion.

Orbit and dynamics

The path is an ellipse reaching 2.543 AU from the Sun at perihelion and 108.6 AU at aphelion, a radial span of 106.1 AU.

Applying Kepler's third law to a = 55.59 AU gives an orbital period of 414 yr, or about 151,386 days.

The high eccentricity (0.954) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

A steep inclination of 98.79° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 26.1 km/s at perihelion and falls to 0.6 km/s at aphelion.

Its Tisserand parameter with respect to Jupiter is T_J = -0.2, a standard discriminator between asteroidal and cometary dynamics.

Size and surface

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

Observation record and orbit quality

The current orbit solution is based on 24 observations and has a weighted RMS residual of 0.545 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.
