Stars & Planet Formation#

Description

We know that Planets forms within Protoplanetary disks (cf video above - Source), that are a by-product of star formation. However, our current understanding of HOW planets are forming is rudimentary at best, and this lack of knowledge is compounded at the very initial stages. For example it is not yet clear how interstellar nm dust grains Insert Drain review on Dust initially present in the solar nebula Insert MMSN ref, can grow by 12 orders of magnitude to many 100’s or 1000’s of km sizes of moons, comets, asteroids and planets present in a mature solar system. One of the major difficulties encountered by scientist is overcoming the Bouncing barrier present around around the cm scale.
