Study Notes
The Solar System
- The Oort Cloud is a distant, spherical shell of icy bodies surrounding the solar system.
- The boundary of the Sun's gravitational influence is the heliopause, which marks the edge of the heliosphere.
- The solar system formed through the process of gravitational collapse of a giant molecular cloud.
- The heliosphere is a region of space influenced by the Sun, comprising the solar wind, the magnetosphere, and the heliopause.
Kuiper Belt and Oort Cloud
- The Kuiper Belt lies past Neptune's orbit in our solar system, a region of icy bodies and other small celestial objects.
