Ch 29: Formation of the Solar System

About This Chapter

Get information on how the solar system was formed, its age and the motion of the planets. Look at the major characteristics of the planets, analyze the Jovian problem and get facts on the condensation sequences.

Formation of the Solar System - Chapter Summary

The lessons in this chapter look at information about the formation and growth of our solar system. Our instructors will go over the solar nebula theory on the solar system's origins and offer ideas on the age of the solar system. They'll look at how the planets could have been formed, and explain planetesimals and protoplanets. Characteristics of the planets and their motions are also discussed. After completing these lessons, you should be able to:

  • Explain the solar nebula theory
  • Understand how to estimate the age of the solar system
  • Explore the condensation sequences and planetary formation
  • Define planetesimals
  • Describe how protoplanets grow
  • Analyze the Jovian problem
  • List characteristics of the solar system's planets
  • Report on patterns of planetary motion

Our instructors have designed brief lessons that are informative and fun. You can study anytime, on a computer or mobile device. The quizzes that accompany each lesson let you assess your knowledge and see what topics require extra help.

Solar System Overview

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.

The Solar Nebula Theory: Formation of the Solar System

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.

What is the Age of the Solar System?

3. 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.

The Condensation Sequences & Planetary Formation

4. 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.

What Are Planetesimals?

5. 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.

How Do Protoplanets Grow?

6. 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!

What Is the Jovian Problem?

7. 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.

Major Characteristics of Planets in the Solar System

8. 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.

Solar Nebula Theory & Patterns of Planetary Motion

9. 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.
