Our solar system would fall apart without the sun. Its gravity is what keeps planets and other celestial bodies moving in orbit. The sun also plays a big role in Earth's weather, climate, and seasons. We wouldn't know of this if we hadn't spent a lot of time over hundreds of years studying the sun. Your young explorers will head to the yellow dwarf star that is our sun with satellites, probes, and through high-powered telescopes. They'll discover what the amazing information missions to and around the sun have taught NASA and space scientists around the world.
