Exploration and discovery of the solar system means learning more about the sun and all of the things around it. The sun is the center of the solar system and its gravity keeps planets, moons, asteroids and comets in their orbits. Exploring and discovering these things means using special tools and machines, like spaceships and telescopes, to look for them and take pictures. This helps us learn more about their size, shape, temperature, distance from the sun, what they're made of, and any unique features. Today, space exploration and discovery is ongoing, with new findings and technology opening up new possibilities.
