Scotti

Scotti follows a distinctly cometary orbit: an eccentricity of 0.252 carries it from 5.036 AU at perihelion out to 8.42 AU at aphelion.

Orbit and dynamics

The path is an ellipse reaching 5.036 AU from the Sun at perihelion and 8.42 AU at aphelion, a radial span of 3.384 AU.

Applying Kepler's third law to a = 6.728 AU gives an orbital period of 17.5 yr, or about 6,374 days.

An eccentricity of 0.252 makes the orbit moderately elongated.

The orbital plane is tilted 9.02° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 14.8 km/s at perihelion and falls to 8.9 km/s at aphelion.

Its Tisserand parameter with respect to Jupiter is T_J = 2.95, a standard discriminator between asteroidal and cometary dynamics.

Size and surface

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

Observation record and orbit quality

The current orbit solution is based on 192 observations and has a weighted RMS residual of 0.4291 arcseconds.

Condition code U = 0 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.
