NASA’s Solar System Interactive (also known as the Orrery) is a live look at the solar system, its planets, moons, comets, and asteroids, as well as the real-time locations of dozens of NASA missions.

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.

Solar System models, especially mechanical models, called orreries, that illustrate the relative positions and motions of the planets and moons in the Solar System have been built for centuries. While they often showed relative sizes, these models were usually not built to scale.

Visualize orbits, relative positions and movements of the Solar System objects in an interactive 3D Solar System viewer and simulator.

Track noteworthy space objects in your browser in a 3D simulation of the solar system.

A beautiful, educational and fun interactive model of the solar system

As you zoom out, the solar system's outer planets – Jupiter, Saturn, Uranus and Neptune – come into view. The date slider allows you to move forwards or backwards by a few months to see the motion of the planets along their orbits.

The best way to understand the true dimensions of the solar system is to create a scale model. Use the tool below to visualize the solar system at various scales.

From the asteroid belt to Jupiter’s turbulent storms, every celestial body sits ready to unfold its story. With the tour continuing to the outer reaches of the universe, you’d experience the icy solitude of the outer planets like Neptune and Uranus. However, we shouldn’t forget about an often overlooked, yet significant part of our solar system.
