What Are Dwarf Planets, Asteroids, Comets, Meteoroids, Meteors, and Meteorites?

The spoken lesson

"Dwarf planets are round worlds orbiting the Sun that have not cleared their orbital neighbourhoods. Asteroids are mainly rocky, metallic, or mixed small bodies. Comets contain volatile ices and may form a glowing coma and tails near the Sun. A meteoroid is a smaller natural object moving through space. When it enters an atmosphere and creates a visible streak, we call the phenomenon a meteor. Any surviving material that reaches the ground is a meteorite. Many asteroids occupy the asteroid belt, while many icy bodies occupy the Kuiper Belt or more distant regions. Astronomers track objects that approach Earth so risks can be studied early. Small solar-system bodies have different compositions, orbits, and names depending on what they are and where they are." DESIGN REQUIREMENTS: Use correct comet-tail direction, realistic asteroid spacing, and one clear meteoroid-to-meteorite sequence. Avoid crowded asteroid fields, every comet tail trailing backward, impact panic, or encouraging rock collection.
