About This Chapter
The Solar System - Chapter Summary
You'll study the solar system when you work through this interesting chapter. Take your time and move at your own pace as you watch videos on the formation of the solar system according to the solar nebula theory, the age of the solar system, and more. These videos are self paced and easy to navigate so you can work on your own timeline as quickly or as slowly as needed. The Dashboard provides a way to monitor your progress through the chapter and submit any questions that you have for one of our instructors to answer. After completing this chapter, you should be able to:
- Discuss the solar nebula theory and patterns of planetary motion
- Explain the condensation sequences and planetary formation
- Detail what planetesimals are
- Describe the process by which protoplanets grow
- Define the Jovian problem
- Outline the major characteristics of planets in the solar system
- Differentiate between the actual and theoretical temperature in our solar system
- Identify the study of celestial bodies and planetary geology
1. Solar System Overview
This lesson will go over the major aspects of our solar system, including the sun, planets, moons, asteroids, comets, meteors, meteorites, and meteoroids.
2. The Solar Nebula Theory: Formation of the Solar System
This lesson will go over the theory that explains how the solar system formed, what theory had once competed with it, and what important implication this theory carries.
3. Solar Nebula Theory & Patterns of Planetary Motion
This lesson will tie together the solar nebula theory and the patterns of motions of the planets in our solar system and why Venus and Uranus are exceptions in the solar system.
4. What is the Age of the Solar System?
This lesson will tell you how old our solar system is and how we know that's the case thanks to radioactive decay, isotopes, half-life, and the solar nebula.
5. The Condensation Sequences & Planetary Formation
In this lesson, you'll learn why the planets have different densities despite being formed from the same solar nebula. We'll cover condensation, uncompressed densities, the ice line, and the condensation sequence.
6. What Are Planetesimals?
This lesson will define what planetesimals are, how they relate to the solar nebula and protoplanets, and how they interacted with one another to eventually help form the planets in our solar system.
7. How Do Protoplanets Grow?
This lesson will teach you about protoplanets, how they formed, and most importantly, how their formation resulted in the planets we see today. We'll also cover outgassing, gravitational collapse, heat of formation, differentiation, and more!
8. What Is the Jovian Problem?
This lesson goes over the two ways the Jovian planets may have formed, called the core accretion model and disk instability model, as well as the Jovian problem and which model solves it.
9. Major Characteristics of Planets in the Solar System
This lesson will go over some characteristics of the planets in our solar system with respect to their masses, diameters, temperatures, densities, and rotation.
10. Theoretical vs. Actual Temperature in our Solar System
This lesson will go over the predicted vs. observed temperature of major celestial bodies in our solar system, if there's a discrepancy between them, and why.
11. Planetary Geology: The Study of Celestial Bodies
Planetary geology is a field of geology that explores celestial bodies like planets, moons, comets, and asteroids. Scientists use a variety of advanced techniques and procedures to carry out their research on these distant bodies.
