Science - Astronomy & Space | | English term or phrase: planetesimal | In cosmogony, planetesimals are objects thought to exist within solar nebulae. Planetesimals are thought to form from the coalescing (due to gravity) of particles, orbiting within the accretion disc of the solar nebula; an accumulation of planetesimals leads to the formation of a protoplanetary disc, which in turn coalesce into protoplanets/planets. Some use the term to refer, in general, to objects such as asteroids and comets; other, such as Comins use the term to refer, specifically, to objects with diameters of ~10km.

Planetesimal
Während der Entstehung der Sonne bildete sich eine flache Gas- und Staubscheibe um die Sonne. Aus dieser Scheibe kondensierten immer grössere Teichen. Durch sanfte Kollisionen bildeten sich aus den Teilchen grössere Brocken, die sogenannten Planetesimale, aus denen wiederum durch Kollisionen untereinander und dem Aufsammeln weiterer Teilchen und Gas schliesslich planetengrosse Körper entstanden. |
