WISE-LINEAR

WISE-LINEAR follows a distinctly cometary orbit: an eccentricity of 0.482 carries it from 2.888 AU at perihelion out to 8.266 AU at aphelion.

Orbit and dynamics

The path is an ellipse reaching 2.888 AU from the Sun at perihelion and 8.266 AU at aphelion, a radial span of 5.378 AU.

Applying Kepler's third law to a = 5.577 AU gives an orbital period of 13.2 yr, or about 4,811 days.

The high eccentricity (0.482) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

The orbital plane is tilted 13.65° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 21.3 km/s at perihelion and falls to 7.5 km/s at aphelion.

Its Tisserand parameter with respect to Jupiter is T_J = 2.7, a standard discriminator between asteroidal and cometary dynamics.

Size and surface

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

Observation record and orbit quality

The current orbit solution is based on 291 observations and has a weighted RMS residual of 0.4685 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.
