Answer:
planetesimal assembly
Explanation:
The accretion model, also known as planetesimal assembly, is what gives us the perspective for the formation of the astronomical objects via the process of accretion. Some of the astronomical objects that are formed by this process are the galaxies, stars, planets,and moons. The process of accretion represents the accumulation of particles into an object by gravitationally attracting more and more matter, mostly gaseous matter, forming an accretion disk.
Answer:
Mercury is the smallest planet, but its surface gravity is about the same as that of the much larger Mars because Mercury is more dense.
hope this helped good luck!
