Take a virtual tour of the solar system starting with detailed information about the sun.

Use the following lithographs to envision the scale of our solar system. View different models of planets at different scales, an infographic about the relative sizes of the planets and distance from the sun, and images of the largest...

Part of a larger online exhibit on the moon and space, this site deals with one's place in the universe. The topics covered include the sun and solar system, the galaxy, and the universe.

Test your knowledge about the solar system with games and activities designed to help explore what you know about the sun, the planets and their moons, space rocks, the Milky Way, and related topics.

Teach the concept of scale models and the size of the solar system through this extensive lesson plan. Students will learn about scale models, estimate which objects to use to create a scale model of Earth and Sun, and figure out how far...

Through a teacher demonstration using water, heat and food coloring, students see how convection moves the energy of the Sun from its core outwards. Students learn about the three different modes of heat transfer (convection, conduction,...

A detailed overview of the history, mythology, and current scientific knowledge of each of the planets and moons in the solar system.

Students explore Mercury and Venus, the first and second planets nearest the Sun. They learn about the planets' characteristics, including their differences from Earth. Students also learn how engineers are involved in the study of...

Learners explore Mars and Jupiter, the fourth and fifth planets from the Sun. They learn some of the unique characteristics of these planets. They also learn how engineers help us learn about these planets with the design and development...

Students explore orbit transfers and, specifically, Hohmann transfers. They investigate the orbits of Earth and Mars by using cardboard and string. Students learn about the planets' orbits around the sun, and about a transfer orbit from...

Besides an introduction to exhibitions and events at the museum, the site provides a guide to stargazing, an astronomy FAQ, space news, virtual tours (see site map) and research resources (including Chinese-English star and constellation...

Enter our solar system to interact with the planets, moons, asteroids, meteors, and more. Investigate with NASA scientists and explore missions related to space exploration. Read facts, compare statistics, look through resources, and...

What makes up the Solar System? Kid astronomers learn about the planets and the sun.

Learn fun facts and details about the weather, geography, composition, and discovery of Mars, the fourth closest planet to the Sun.

In this lesson plan site, students are asked to construct a scale model of the planets to help visualize the relative size of planets and their relative distance from the Sun. Links are provided to the Sun and the planets which contain...

Students are introduced to our Sun as they explore its composition, what is happening inside it, its relationship to our planet (our energy source), and the ways engineers help us learn about it.

Create a classroom model of the solar system while teaching about relative size of all the planets, and each planet's distance from the sun.

The Earth's atmosphere is a thin layer of gases that surrounds the Earth. It composed of 78% nitrogen, 21% oxygen, 0.9% argon, 0.03% carbon dioxide, and trace amounts of other gases. This thin gaseous layer insulates the Earth from...

Even with disruptions like weather fronts and storms, there is a consistent pattern to how air moves around our planet's atmosphere. This pattern, called atmospheric circulation, is caused because the Sun heats the Earth more at the...
