About the The Solar System Explained Course

The Solar System Explained is a Science course that gives students a clear, practical tour of planets, moons, orbits, space environments, and exploration with Professor Victor Zane. Through focused lessons, you will build a confident understanding of how our solar system formed, how it works, and why it continues to shape modern discovery.

Explore The Solar System Through Evidence And Discovery

  • Understand the foundations of gravity, orbits, cosmic motion, and our place in space.
  • Compare rocky planets, giant planets, ice giants, moons, asteroids, comets, and distant icy worlds.
  • Learn how spacecraft, planetary defense, and scientific evidence reveal the history of solar system worlds.
  • Build practical Science knowledge for astronomy, space exploration, and planetary habitability.

A clear, practical tour of planets, moons, orbits, space environments, and exploration with Professor Victor Zane.

This course begins with the foundations of the Solar System, helping you map Earth’s place in space and understand the forces that govern planetary motion. You will study gravity, orbits, and cosmic motion before moving into the birth of the Solar System and the role of the Sun as its central engine.

From there, The Solar System Explained examines the inner rocky worlds, including Mercury, Venus, Earth, the Moon, and Mars. You will explore planetary survival, runaway greenhouse conditions, impact history, climate change, water, and the search for evidence beyond Earth.

The course also covers asteroids, meteorites, Jupiter, Saturn, Uranus, Neptune, ocean worlds, comets, Kuiper Belt objects, Pluto, and near-Earth objects. Along the way, Professor Victor Zane connects each topic to the Science of exploration, showing how spacecraft missions and planetary evidence help us understand both ancient history and future discovery.

By the end of the course, you will be able to explain the major worlds and small bodies of the Solar System with clarity, compare their environments, and understand how scientists investigate planets, moons, habitability, and space hazards. You will leave with a stronger, more practical Science perspective on the Solar System and your place within it.

Full lesson breakdown

Lessons are organized by topic area and each includes descriptive copy for search visibility and student clarity.

Foundations of the Solar System

2 lessons

This lesson builds the basic map learners will use throughout the course: where Earth sits, what counts as the Solar System, how distances are measured, and why scale matters. Professor Victor Zane in…
Gravity is the organizing force of the Solar System. It holds planets around the Sun, moons around planets, rings around giant worlds, and spacecraft on carefully planned paths. This lesson explains g…

Origins and Structure

2 lessons

In this lesson, Professor Victor Zane explains how the Solar System formed from a cold, rotating cloud of gas and dust about 4.6 billion years ago. The lesson follows the sequence from nebula collapse…
In this lesson, Professor Victor Zane explains why the Sun is the central engine of the solar system: it contains almost all of the system’s mass, supplies nearly all incoming energy, and shapes plane…

The Inner Rocky Worlds

5 lessons

Mercury is the closest planet to the Sun and one of the best places to study how rocky worlds survive under extreme conditions. This lesson explains why Mercury is not simply a hot version of the Moon…
Venus is often called Earth’s twin because the two planets are similar in size, mass, and rocky composition, but their surface conditions could hardly be more different. This lesson explains how Venus…
Earth is not just our home world; it is the reference point scientists use to understand the other rocky planets. In this lesson, Professor Victor Zane explains how Earth’s size, density, atmosphere, …
This lesson uses the Moon as a practical record book for the inner Solar System. Students learn why the Moon preserves ancient impact scars so well, how craters form, what maria and highlands reveal a…
In this lesson, Professor Victor Zane examines Mars as a world shaped by climate change, ancient water, active surface processes, and careful scientific investigation. The focus is not on Mars as a sc…

Small Bodies and Ancient Evidence

2 lessons

Asteroids and meteorites are among the Solar System's best records of its earliest construction. This lesson explains what asteroids are, where they are found, how meteorites reach Earth, and why smal…
This lesson examines the icy small bodies beyond the main planets: comets, Kuiper Belt objects, dwarf planets, centaurs, and other distant worlds. Students learn how these objects preserve evidence fr…

The Giant Planets

2 lessons

Jupiter is the Solar System's largest planet and the clearest example of a world that behaves almost like a small system of its own. This lesson explains Jupiter's bulk composition, rapid rotation, ba…
Saturn is the Solar System’s most visually famous planet, but its rings are only one part of a much larger, active system. This lesson explains Saturn as a low-density gas giant, the structure and beh…

The Outer Solar System

2 lessons

This lesson examines Uranus and Neptune as the Solar System’s ice giants : worlds larger than Earth but different from Jupiter and Saturn in composition, structure, climate, and magnetic behavior. Stu…
This lesson explains why Pluto was long treated as the ninth planet, what new discoveries in the outer Solar System revealed, and why astronomers changed the formal definition of a planet in 2006. Stu…

Moons and Habitability

1 lesson

This lesson examines why several icy moons are considered some of the most promising places to search for life beyond Earth. Instead of focusing on sunlight at a planet’s surface, Professor Victor Zan…

Exploration and Evidence

2 lessons

Spacecraft turn distant planetary worlds into measurable evidence. This lesson explains how flybys, orbiters, landers, rovers, atmospheric probes, and sample-return missions work, and why each design …
This lesson explains planetary defense as an evidence-driven process: find near-Earth objects early, calculate whether any pose a real impact risk, characterize their size and behavior, and choose a r…

Synthesis and Future Discovery

1 lesson

This lesson pulls the course together by placing the Solar System in its larger scientific context: one planetary system among many, shaped by gravity, chemistry, impacts, radiation, and time. Profess…
