Relationships, not isolated facts
This viewport is generated from the Asteria knowledge graph. Science, culture, and interpretive links remain separated by domain so visual context never changes the evidentiary meaning of a relation.

comet classJupiter-Family Comets
The most numerous class of periodic comets, whose orbits are shepherded by Jupiter and which originate in the scattered disc beyond Neptune.
minor planet groupScattered Disc
A sparse population of distant icy bodies on eccentric, inclined orbits, gravitationally scattered outward by Neptune — the likely source of many short-period comets.
timeline eventRosetta and Philae Reach a Comet
ESA's Rosetta becomes the first spacecraft to orbit a comet and, with its Philae lander, the first to soft-land on one — comet Churyumov–Gerasimenko.
mission milestoneFirst Comet Landing
Rosetta's Philae lander made the first soft landing on the nucleus of a comet.
