Lagerkvist

Lagerkvist follows a distinctly cometary orbit: an eccentricity of 0.31 carries it from 2.61 AU at perihelion out to 4.954 AU at aphelion.

Orbit and dynamics

Between its closest point (2.61 AU) and its farthest (4.954 AU), the heliocentric distance changes by 2.344 AU over every revolution.

One full revolution takes 7.35 yr (2,686 days), computed from the semi-major axis of 3.782 AU.

An eccentricity of 0.31 makes the orbit moderately elongated.

Its inclination of 2.61° keeps it close to the plane of the ecliptic.

By the vis-viva equation its orbital speed rises to 21.1 km/s at perihelion and falls to 11.1 km/s at aphelion.

Its Tisserand parameter with respect to Jupiter is T_J = 3, a standard discriminator between asteroidal and cometary dynamics.

Size and surface

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

Observation record and orbit quality

Astrometry from 137 individual observations underpins this orbit; the fit leaves an RMS residual of 0.7531 arcseconds.

Condition code U = 5 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.
