Solar System Origins: From Interstellar Cloud to Planetary Formation

Explore the fascinating journey from the collapsing interstellar cloud to the formation of our solar system. Learn how gravity condenses the cloud and initiates spinning, leading to planetesimal formation and eventually the birth of inner and outer planets. Witness how debris in the asteroid belt shapes the evolution of our planetary system.

Presentation Transcript

  1. Formation of Our Solar System

  2. Collapsing Interstellar Cloud • An Interstellar Could is a collection of gas and dust between stars. • Gravity can cause the interstellar cloud to condense and collapse

  3. Spinning Interstellar Cloud • The cloud will begin to rotate spin faster forming a dense concentration at the center. • This Solar Nebula would become the Sun Check This Out

  4. Planet Formation • As the temperatures cooled and the Sun’s gravity pulled objects closer, planetesimals began to form

  5. Planetesimals into Planets • The Planetesmials would form into inner and outer planets: • Inner –Mercury, Venus, Earth, Mars • Outer- Jupiter, Saturn, Uranus, Neptune

  6. Inner Planets • Are made primarily of rocky dense material. • Most inner planets do not have moons because the Sun’s gravity absorbed these satellites.

  7. Outer Planets • The first large planet to form was Jupiter. It grew over time by attracting icy planetesimals. • The other outer planets couldn’t grow as large because of Jupiter’s gravity

  8. Debris • Not all planetesimals turned to planets. • There is an asteroid belt between the inner and outer planets. • Jupiter’s gravity prevented this debris from becoming a planet
