Orbit and dynamics
Between its closest point (5.238 AU) and its farthest (802.7 AU), the heliocentric distance changes by 797.5 AU over every revolution.
One full revolution takes 8,120 yr (2,965,939 days), computed from the semi-major axis of 404.0 AU.
The high eccentricity (0.987) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
A steep inclination of 39.2° carries it well above and below the ecliptic plane.
By the vis-viva equation its orbital speed rises to 18.3 km/s at perihelion and falls to 0.1 km/s at aphelion.
Its Tisserand parameter with respect to Jupiter is T_J = 2.21, 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 11 individual observations underpins this orbit; the fit leaves an RMS residual of 0.5164 arcseconds.
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.
