Disentangling the Early History of the Solar System
Giant planets form out of a disc of gas and dust – called protoplanetary disc -- that surrounded the protosun at the time of its formation. While the cores of giant planets were growing via planetesimal and pebble accretion, they started to interact with the gas in the protoplanetary disc. These interactions can lead to inward migration of all the four giant planets in our Solar System during the
