1. Nebulae: These are giant clouds of gas and dust. Some are the birthplaces of stars, while others are the remnants of exploded stars. They come in various shapes and colors, like the famous Crab Nebula.
2. Asteroids: These are rocky bodies that orbit the Sun, mainly found in the asteroid belt between Mars and Jupiter. They range in size from pebbles to dwarf planets like Ceres.
3. Comets: These are icy bodies that also orbit the Sun. When they get close enough, they heat up, releasing gas and dust that forms a visible tail. They are often called "dirty snowballs."
