  2. WARM-UP # 32 Which planets are the terrestrial planets and which planets are the gas planets? What are three of their primary differences? The terrestrial planets are made of rock, smaller, closer together, do not have rings, and are closer to the sun. The gas giants are made of gas, huge, farther apart, all have rings, and are farther from the sun.

  3. Pluto does not clear its orbit. There are many space objects in Pluto’s orbit. WARM-UP # 33 Why isn’t Pluto a planet anymore? What makes it a dwarf planet?

  4. WARM-UP # 34 What is a light year? A light year is the distance that light travels in one year.

  5. WARM-UP # 35 A – How many asteroids are in the asteroid belt? Over 1 million B – Why does Mars have seasons? Tilt and revolution

  6. WARM-UP # 36 What is a star? A star is a large, hot ball of gas which is held together by its own gravity and gives off its own light.

  7. Warm-UP #37 What is the asteroid belt from? The remains of a 5th terrestrial planet

  8. WARM-UP # 38 What is the magnitude of a star? What is the difference between apparent magnitude and absolute magnitude? The magnitude of a star is the BRIGHTNESS. ABSOLUTE – actual brightness APPARENT – how bright is appears
