La Sagra

La Sagra follows a distinctly cometary orbit: an eccentricity of 0.769 carries it from 1.755 AU at perihelion out to 13.437 AU at aphelion.

Orbit and dynamics

Between its closest point (1.755 AU) and its farthest (13.437 AU), the heliocentric distance changes by 11.682 AU over every revolution.

One full revolution takes 20.9 yr (7,647 days), computed from the semi-major axis of 7.596 AU.

The high eccentricity (0.769) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

A steep inclination of 28.11° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 29.9 km/s at perihelion and falls to 3.9 km/s at aphelion.

Its Tisserand parameter with respect to Jupiter is T_J = 2.05, a standard discriminator between asteroidal and cometary dynamics.

Size and surface

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

Observation record and orbit quality

Astrometry from 882 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4458 arcseconds.

Condition code U = 3 indicates a moderately constrained orbit; predictions decades ahead still carry noticeable uncertainty.

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.
