In Depth | Our Solar System – NASA Solar System Exploration
Most of the hundreds of billions of stars in our galaxy are thought to have planets of their own, and the Milky Way is but one of perhaps 100 billion galaxies in the universe.
In Depth | Sun – NASA Solar System Exploration
The Sun orbits the center of the Milky Way, bringing with it the planets, asteroids, comets, and other objects in our solar system. Our solar system is moving with an average velocity of 450,000 miles per hour (720,000 kilometers per hour).

Science Overview Voyage is a 1 to 10-billion scale model of the Solar System that was permanently installed in Washington, D.C., in October 2001. The real Solar System is exactly 10 billion times larger than the Voyage model. On this scale the Sun is about the size of a large grapefruit. The Earth is 15 meters (50 feet) away and smaller than the head of a pin. The entire orbit of the Moon fits ...

Psyche Raw Images – NASA Solar System Exploration
Currently, the spacecraft is on its way to its destination, asteroid Psyche. The images taken during the cruise phase of the mission mostly show star fields, and occasionally a planet - like Jupiter - that will look like a distant star.

This program allowed her to introduce NASA and their Space Program to students by way of Starlab. Starlab was an in-person interactive visual experience allowing students to see and learn about various aspects of space.
Although most stars in the sky, like our Sun, appear to shine steadily ...
