Hi Phoebe! Today we're going on a super-fast tour of some amazing moons in our solar system – and one of them even shares your name!
Materials Quick Check:
- Computer/Tablet with Internet
- Paper
- Colored Pencils or Markers
(2 mins) Earth's Moon and Beyond:
You know our Moon, right? It's Earth's only natural satellite. But did you know other planets have moons too? Some have LOTS! Let's start our tour.
(5 mins) Gas Giant Moons - Jupiter & Saturn:
Let's visit the biggest planets!
- Jupiter: Has nearly 100 moons! Let's look up Jupiter's moon Io (pronounced EYE-oh). (Quick search for NASA images/info on Io). What's really cool about Io? It's the most volcanically active body in the entire solar system! Imagine volcanoes erupting constantly.
- Saturn: Famous for its rings, Saturn also has over 100 moons! One really interesting one is Titan. (Quick search for NASA images/info on Titan). Titan is unique because it has a thick atmosphere, sort of like Earth, and even has lakes and rivers made of liquid methane! Brrr!
(5 mins) Phoebe Meets Phoebe!:
Now for a special moon – one of Saturn's moons is named Phoebe! (Quick search for NASA images/info on Saturn's moon Phoebe). Look at its picture. What do you notice?
- It's not very round, is it? It's kind of lumpy!
- It orbits Saturn backwards compared to most of its other large moons (this is called a 'retrograde' orbit).
- It's very dark.
Scientists think Phoebe might actually be a captured object from the outer solar system, called a Kuiper Belt Object, rather than forming with Saturn. So cool that you share a name with such an interesting moon!
(5 mins) Ice Giants' Moons - Uranus & Neptune:
Let's zoom further out!
- Uranus: Has moons often named after characters from Shakespeare. Miranda is a strange one – it looks like it was smashed apart and put back together! (Optional: Quick search for Miranda image).
- Neptune: Its largest moon, Triton, also orbits backwards (like Phoebe!) and has icy geysers that shoot nitrogen frost! (Optional: Quick search for Triton image).
See? Moons aren't just round rocks like ours. They can be volcanic, have atmospheres, orbit backwards, and look totally weird!
(3 mins) Your Favorite Moon & Wrap-up:
Quick! Grab your paper and colors. Draw one of the moons we talked about (or invent your own moon around another planet!). While you draw, tell me one cool fact you remember about any of the moons we visited.
Great job, Phoebe! Today we learned that planets have lots of different moons, like volcanic Io, hazy Titan, and the special, lumpy, backward-orbiting Phoebe. What an amazing solar system!
