WHAT DOES PLANETESIMAL MEAN IN ENGLISH?

planetesimal

Planetesimal

Planetesimals /plænɨˈtɛsɨməlz/ are solid objects thought to exist in protoplanetary disks and in debris disks. Debris disks detected in HST archival images of young stars, HD 141943 and HD 191089, using improved imaging processes. A widely accepted theory of planet formation, the so-called planetesimal hypotheses, the Chamberlin–Moulton planetesimal hypothesis and that of Viktor Safronov, states that planets form out of cosmic dust grains that collide and stick to form larger and larger bodies. When the bodies reach sizes of approximately one kilometer, then they can attract each other directly through their mutual gravity, enormously aiding further growth into moon-sized protoplanets. This is how planetesimals are often defined. Bodies that are smaller than planetesimals must rely on Brownian motion or turbulent motions in the gas to cause the collisions that can lead to sticking. Alternatively, planetesimals can form in a very dense layer of dust grains that undergoes a collective gravitational instability in the mid-plane of a protoplanetary disk.

Definition of planetesimal in the English dictionary

The definition of planetesimal in the dictionary is any of a number of small bodies formerly thought to have been drawn from the sun by the close passage of a star to the sun, eventually coalescing to form the planets.
