Who Am I? Naming the Planets Worksheet
The first worksheet will have kids read eight clues, one for each planet, and write the correct planet name on the line.
The clues include:
- distinguishing physical features
- composition (rocky or gas)
- temperature
- fun facts
- interesting comparisons

This riddle-style activity encourages kids to think critically while applying what they already know about the planets.
Name and Order of Planets Worksheet
The next worksheet focuses on remembering the names of the eight planets and placing them in order from the Sun.
Kids will:
- identify each illustrated planet
- write its name
- number the planets 1–8 based on their order from the Sun

This page is perfect for helping students remember the correct sequence of the planets.
Planets of the Solar System Worksheet
The final page packs in a lot of learning. Students will need to identify the correct planet that matches each clue.
For example, which planet in our solar system is the largest, and which is the smallest? Which planets do not have moons?
There’s also a small section on planets with moons. It’s a good way to introduce the solar system’s moons without overwhelming kids with too many numbers or complex details.

And which planets have rings? The planets worksheet includes a mini chart with some details about each planet’s rings.
However, the planet names are missing. So students will need to read the clues and write the correct planet names.
To add some fun, the worksheet includes 2 space themed mazes.
