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!

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.
