The course deals with the physical processes inside the Solar System, from its formation to present processes, also in comparison with exoplanetary systems. The subject of life in the Universe is also approached. The subjects include also recent findings from dedicated space missions.
Knowledge and understanding:
the Student must demonstrate knowledge and understanding of the fundamentals physical science in the Solar System.
Ability to apply knowledge and understanding:
the Student must demonstrate to be able to use his own acquired knowledge to discuss and explain the main past and active physical processes in the Solar System and place them in the broader context of planetary systems in the Universe.
Independent judgment: the Student must be able to know how to independently evaluate point of views and applications different from the ones presented by the Teacher during the lessons.
Communication Skills: the Student should be able to support a conversation on the lessons topics using a correct scientific language with corresponding mathematical and graphical representation.
Learning Skills: the Student must be able to update and deepen autonomously specific topics and applications dealing with the studied subjects.
The Student must know the basic mathematics and physics, kinematics, dynamics of the point ant the rigid body, electromagnetism.

The purpose of the test procedure is quantifying the level of achievement of the educational objectives aforementioned. The test procedure is an oral examination dealing with the subjects of the lessons.
The lessons will be held in italian. The Teacher is anyway available to interact in english with foreign students at any level, from the lessons to the final examination.
