WebApr 25, 2024 · Planetesimal matter such as rock and dust may have combined with gravity to form a number of the masses orbiting the sun. Planetesimal Particulars Russian astronomer Viktor Safronov theorized that, when the solar system was forming, the attractive force of gravity pulled bits from nebulae --clouds of dust, gasses and plasma-- … WebHowever, for this specific journey, scientists believe a larger planetesimal might have had some close encounters with other gas giants of the system, so close that the gravitational pull from the planets would have stretched and shredded the object into pieces. Planetesimals /plænɪˈtɛsɪməlz/ are solid objects thought to exist in protoplanetary disks and debris disks. Per the Chamberlin–Moulton planetesimal hypothesis, they are believed to form out of cosmic dust grains. Believed to have formed in the Solar System about 4.6 billion years ago, they aid study of its formation.
