PPT-The solar system formed from the collapse of an interstellar cloud.

Section 1 Formation of the Solar System K What I Know W What I Want to Find Out L What I Learned Essential Questions How did the solar system form How are early concepts of the structure of the solar system described. Our Solar System and Its Origin. . How was the Solar System Formed?. A viable theory for the formation of the solar system must be . based on physical principles (conservation of energy, momentum, the law of gravity, the law of motions, etc.), . The processes by which stars and planets form are active areas of research in modern astrophysics. The formation of our own solar system is central to the first half of our course, and important to the second half as well when we study the formation of stars. : . theory and. IBEX (NASA) and. . Voyager (NASA) data analyses. Izmodenov V.V.. Space Research Institute (IKI) RAS. &. Lomonosov Moscow State University. 2. Subject: the region where the solar wind interacts with the local interstellar medium. The Interstellar Medium. Credits: Much of this slideset is modified from lectures by Dr. Peter Newbury (UBC). The Interstellar Medium. The . matter that exists in the space between the star systems in a galaxy. This matter includes gas in ionic, atomic, and molecular form, as well as dust and cosmic rays. Solar System:. The sun and all of the planets and other bodies that travel around it. Planet. A celestial body that orbits the sun, is round because of its own gravity, and has cleared the neighborhood around its orbital path. Solutions. 1. Describe . the focus of comparative . planetology. and discuss its importance to solar system studies. .. Comparative . planetology. is . the approach we use to study and understand our solar system. Nebula . Theory. Summing Up. SNT Explaining the Solar System. The Solar System’s disk shape. Inherited from the motion of materials in the solar nebula. . The planets and moons mostly rotate and revolve in the same directions because they evolved from the same gas cloud. . 25.5. Any theory about the origin of the solar system must explain. why all of the planets’ orbits lie more or less in a plane . Why all of the planets orbit the sun in the same direction. . It must also explain the differences in size and composition between the terrestrial planets and the gas giants.. Part II: Interstellar . Gas. . . Gas . Absorbing. Light. In addition to dust grains, there is low-density gas between the stars. . This leads to the formation of . additional . absorption . lines in the spectrum of a star. © 2015 Pearson Education, Inc.. 6.1 A Brief Tour of the Solar System. Our goals for learning:. What does the solar system look like?. © 2015 Pearson Education, Inc.. What does the solar system look like?. The Oort Cloud. What is the Oort Cloud?. Spherical area between 5,000 and 100,000 AU from the sun (Kuiper belt ends at 55 AU). Proxima Centauri is 270,000 AU from sun. Contains between 0.1 and 2 trillion comets. The processes by which stars and planets form are active areas of research in modern astrophysics. The formation of our own solar system is central to the first half of our course, and important to the second half as well when we study the formation of stars.
