Educational worksheet about the solar system and planets.

Let’s go step by step through each question.

Tuesday Section

Question 1:
*The object in the center of our solar system is...*
We know from science that the Sun is at the center, and all planets orbit around it.
→ Correct answer: c. the Sun

---

Question 2:
*Put a check next to objects that revolve (move) around the Sun. Do NOT check those that do not.*

Let’s think about each one:

- a. Earth → YES, orbits the Sun ✔
- b. asteroids in the asteroid belt → YES, they orbit the Sun ✔
- c. the Milky Way → NO, that’s our galaxy — the whole solar system moves inside it, but it doesn’t orbit the Sun ✘
- d. Pluto → YES, even though it’s a dwarf planet, it still orbits the Sun ✔
- e. Andromeda → NO, that’s another galaxy far away ✘
- f. Mercury → YES, closest planet to the Sun ✔
- g. a black hole → NO, unless it’s part of our solar system (it’s not), so no ✘
- h. Jupiter → YES, largest planet, orbits the Sun ✔
- i. comets → YES, they have long orbits around the Sun ✔

So checked items: a, b, d, f, h, i
Unchecked: c, e, g

Question 3:
*We say the planets revolve or ______ around the Sun.*
“Revolve” means to move in a circle around something. The word we use for that path is “orbit.”
→ Correct answer: b. orbit

Wednesday Section

Question 1:
We are given a diagram with letters a–i showing planets in order from the Sun (closest to farthest). We must match them using this list:
Earth, Uranus, Mercury, Pluto, Jupiter, Mars, Venus, Neptune, Saturn

Remember the correct order of planets from the Sun:
1. Mercury
2. Venus
3. Earth
4. Mars
5. Jupiter
6. Saturn
7. Uranus
8. Neptune
9. Pluto (even though it’s now called a dwarf planet, it’s included here)

Now match to the diagram:

Looking at the image description (we can infer positions):

- a = closest to Sun → Mercury
- b = second → Venus
- c = third → Earth
- d = fourth → Mars
- e = fifth → Jupiter
- f = sixth → Saturn (has rings!)
- g = seventh → Uranus
- h = eighth → Neptune
- i = ninth/farthest → Pluto

So:

a. Mercury
b. Venus
c. Earth
d. Mars
e. Jupiter
f. Saturn
g. Uranus
h. Neptune
i. Pluto

Question 2:
*All these planets...*
Options:
a. are made of rock → No, gas giants like Jupiter aren’t mostly rock ✘
b. give off light and heat → No
