Lagerkvist-Carsenty

Lagerkvist-Carsenty follows a distinctly cometary orbit: an eccentricity of 0.362 carries it from 4.257 AU at perihelion out to 9.093 AU at aphelion.

Orbit and dynamics

The path is an ellipse reaching 4.257 AU from the Sun at perihelion and 9.093 AU at aphelion, a radial span of 4.836 AU.

Applying Kepler's third law to a = 6.675 AU gives an orbital period of 17.2 yr, or about 6,299 days.

An eccentricity of 0.362 makes the orbit moderately elongated.

Its inclination of 4.84° keeps it close to the plane of the ecliptic.

By the vis-viva equation its orbital speed rises to 16.8 km/s at perihelion and falls to 7.9 km/s at aphelion.

Its Tisserand parameter with respect to Jupiter is T_J = 2.88, a standard discriminator between asteroidal and cometary dynamics.

Size and surface

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

Observation record and orbit quality

The current orbit solution is based on 369 observations and has a weighted RMS residual of 0.5071 arcseconds.

Condition code U = 1 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.
