Larsen

Larsen is catalogued in the JPL Small-Body Database as a comet object; the orbital elements available for it are listed below.

comet Observations: 109
Eccentricity · e
1.0023

Orbit and dynamics

The path is an ellipse reaching 5.768 AU from the Sun at perihelion and -5,035.8 AU at aphelion, a radial span of -5,041.6 AU.

The high eccentricity (1.002) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

A steep inclination of 113.4° carries it well above and below the ecliptic plane.

Size and surface

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

Observation record and orbit quality

The current orbit solution is based on 109 observations and has a weighted RMS residual of 0.7607 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.
