The Pluto problem

Question: how big is Pluto? Not very big! Its actually smaller than Russia!

Pluto is smaller than the moon, but that doesn’t mean that Pluto is a moon! What does it mean to be a planet? Planets orbit the Sun, are spherical, and have ‘cleaned up’ all rocks around it (such as asteroids) Dwarf Planets like Pluto also orbit the Sun, but they’re not big enough to hoover up all the other debris close by it. Moons can be any size and shape, and circle around a planet or a dwarf planet. Most of Jupiter’s moons are in fact larger than Pluto!

Our Solar System Which of these produces their own light? If something produces its own light, we say that it is luminous. For example; the Sun is luminous. How do we see the other objects in the Solar System? They reflect the light from the Sun.

Our Solar System Our solar system has ______ planets and thousands of ___________, which are small lumps of rock found between _________ and Jupiter. All the planets and asteroids _______ around the Sun. The Sun is a ______ so it produces its own _______. We can only see planets when they _________ light from the Sun. Earth nine Mars reflect orbit star light asteroids

Question: what are the Northern (and Southern) lights? The Sun creates so much energy, it often pushes particles towards Earth. When they hit Earth atmosphere, Earth’s magnetic field sends them to the North and South poles, where they undergo a chemical reaction with particles in the atmosphere and create different coloured light.
