The Solar System Overview

The solar system consists of the Sun and orbiting bodies.

The Voyager 1 spacecraft, launched in 1977, has been traveling through space for over 40 years and has entered the interstellar medium, the region of space outside our solar system, which is made up of the Sun and orbiting bodies such as planets, moons, asteroids, and comets.

These orbiting bodies are held in their orbits by the gravitational force of the Sun, which is the center of our solar system.

The solar system is a complex and dynamic system, with many different types of objects interacting with each other through gravity and other forces.
