Lynn

Lynn follows a distinctly cometary orbit: an eccentricity of 0.997 carries it from 0.761 AU at perihelion out to 593.4 AU at aphelion.

Orbit and dynamics

The path is an ellipse reaching 0.761 AU from the Sun at perihelion and 593.4 AU at aphelion, a radial span of 592.7 AU.

Applying Kepler's third law to a = 297.1 AU gives an orbital period of 5,121 yr, or about 1,870,442 days.

The high eccentricity (0.997) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

A steep inclination of 111.7° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 48.3 km/s at perihelion and falls to 0.1 km/s at aphelion.

Because q < 1 AU and Q > 1 AU, this orbit geometrically intersects the region of Earth's orbit.

Its Tisserand parameter with respect to Jupiter is T_J = -0.38, a standard discriminator between asteroidal and cometary dynamics.

Size and surface

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

Observation record and orbit quality

The current orbit solution is based on 203 observations and has a weighted RMS residual of 0.7895 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.
