NEAT-LINEAR

NEAT-LINEAR follows a distinctly cometary orbit: an eccentricity of 0.559 carries it from 3.369 AU at perihelion out to 11.917 AU at aphelion.

Orbit and dynamics

The path is an ellipse reaching 3.369 AU from the Sun at perihelion and 11.917 AU at aphelion, a radial span of 8.548 AU.

Applying Kepler's third law to a = 7.643 AU gives an orbital period of 21.1 yr, or about 7,718 days.

The high eccentricity (0.559) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

The orbital plane is tilted 10.9° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 20.3 km/s at perihelion and falls to 5.7 km/s at aphelion.

Its Tisserand parameter with respect to Jupiter is T_J = 2.65, a standard discriminator between asteroidal and cometary dynamics.

Size and surface

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

Observation record and orbit quality

The current orbit solution is based on 1,350 observations and has a weighted RMS residual of 0.709 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.
