The Sun at the heart of our solar system is a yellow dwarf star, a hot ball of glowing gases. Its gravity holds the solar system together. Learn about all there is in the solar system.
All About the Planets
The solar system is the Earth's little neighborhood. So it makes sense that scientists know more about the solar system than any where else. Explore what we know with NASA!
How Does Gravity Affect Objects in Space?
How do celestial bodies warp the fabric of space-time and interact with each other?

Use the virtual lab to create objects in space and begin creating your universe/solar system. Be careful, gravity is everywhere!
Create Your Own Solar System
Use the virtual lab to create your own solar system and begin observing how the laws of physics work and how planets interact. 
Solar System Scope
View the motion of the planets in this activity. Solar System Scope is a model of Solar System, Night sky and Outer Space in real time, with accurate positions of objects and lots of interesting facts.
