Let’s go through each clue one by one and match it to the correct planet.

1. The largest planet in the solar system.
→ That’s Jupiter! It’s way bigger than all the others.

2. The sixth planet from the sun in the solar system.
→ Counting from the Sun: Mercury (1), Venus (2), Earth (3), Mars (4), Jupiter (5), Saturn (6). So, Saturn!

3. The brightest planet in the solar system.
→ Venus is often called the “Morning Star” or “Evening Star” because it shines so brightly in our sky.

4. The planet with the nickname “Red Planet”.
→ That’s Mars — it looks red because of iron oxide (rust) on its surface.

5. The coldest planet in the solar system.
→ Neptune is farthest from the Sun (usually — see #8), so it gets very cold. But wait — Pluto is even colder, but it’s not a planet anymore. Among the 8 planets, Neptune is the coldest.

6. A dwarf planet in the solar system.
→ Pluto is the most famous dwarf planet. The list includes it, so we’ll pick Pluto.

7. The planet closest to the sun in the solar system.
→ That’s Mercury — it zips around the Sun faster than any other planet.

8. The planet farthest from the sun in the solar system.
→ Since Pluto is now classified as a dwarf planet, Neptune is the farthest official planet.

9. The only known planet to support life.
→ That’s Earth — we live here, and no other planet has been found with life yet.

Now let’s double-check:

- Largest → Jupiter ✔
- Sixth from Sun → Saturn ✔
- Brightest → Venus ✔
- Red Planet → Mars ✔
- Coldest → Neptune ✔ (Pluto is colder but not a planet)
- Dwarf planet → Pluto ✔
- Closest to Sun → Mercury ✔
- Farthest from Sun → Neptune ✔
- Supports life → Earth ✔

Wait — hold on! We have two clues pointing to Neptune (#5 and #8). Is that okay? Yes — because Neptune *is* both the coldest and the farthest planet (since Pluto isn’t counted as a planet anymore).

Also, note: In the image, “Mercury” is misspelled as “Mecury” — but we know it means Mercury.

Final matches:

1. Jupiter
2. Saturn
3. Venus
4. Mars
5. Neptune
6. Pluto
7. Mercury
8. Neptune
9. Earth

But wait — can Neptune be used twice? In matching exercises like this, sometimes you’re supposed to use each option once. Let’s check the list again.

Looking at the right-hand side, there are 9 options: Mecury (Mercury), Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto.

We have 9 questions and 9 answers — so each should be used once.

That means we made a mistake.

Clue #5: “The coldest planet in the solar system.”

If we assign Neptune to #8 (farthest), then what about #5?

Actually, Uranus is sometimes considered colder than Neptune because of how it rotates and lacks internal heat — but generally, Neptune is accepted as the coldest.

However, for school-level worksheets, they usually expect:

- Coldest = Neptune
- Farthest = Neptune

But since we can’t use Neptune twice, maybe the worksheet expects:

#5: Uranus (as coldest)
#8: Neptune (as farthest)

Wait — let’s think differently.

In many elementary curricula, they teach:

- Farthest planet = Neptune
- Coldest planet = Neptune

But if we must assign unique answers, perhaps the worksheet intends:

#5: Uranus — because some sources say Uranus is colder due to its tilt and lack of internal heat.

Actually, scientifically, Neptune is slightly colder on average than Uranus.

But for simplicity in schools, they might pair:

#5: Neptune (coldest)
#8: Neptune (farthest) — but that’s duplicate.

Alternatively, maybe #5 is meant to be Pluto? But Pluto is listed separately as a dwarf planet.

Wait — look at clue #6: “A dwarf planet in the solar system.” → That’s clearly Pluto.

So Pluto is taken.

Then for #5 and #8, we need two different planets.

Perhaps the worksheet considers Uranus as the coldest? Let me check common teaching materials.

Upon second thought — in many K-8 worksheets, they simplify and say:

- Coldest = Neptune
- Farthest = Neptune

But since we have to match uniquely, and Uranus is also very cold, maybe the intended answer is:

#5: Uranus
#8: Neptune

Yes — that makes sense for a matching exercise where each answer is used once.

Let’s verify with standard facts taught in schools:

- Uranus: tilted on its side, very cold, sometimes called the coldest.
- Neptune: farthest, also very cold.

Some sources say Uranus holds the record for lowest temperature measured (-224°C vs Neptune’s -214°C).

So for accuracy in a school context, we’ll go with:

#5: Uranus (coldest)
#8: Neptune (farthest)

That way, all 9 answers are unique.

Let’s redo the full matching with unique assignments:

1. Largest → Jupiter
2. Sixth from Sun → Saturn
3. Brightest → Venus
4. Red Planet → Mars
5. Coldest → Uranus (based on recorded temps)
6. Dwarf planet → Pluto
7. Closest to Sun → Mercury
8. Farthest from Sun → Neptune
9. Supports life → Earth

Perfect — all 9 used once.

Double-check order from Sun:

1. Mercury
2. Venus
3. Earth
4. Mars
5. Jupiter
6. Saturn
7. Uranus
8. Neptune

Yes — so sixth is Saturn, farthest is Neptune.

Coldest: Uranus has lower minimum temp than Neptune.

Brightest: Venus — yes.

Red Planet: Mars — yes.

Dwarf planet: Pluto — yes.

Supports life: Earth — yes.

Closest: Mercury — yes.

Largest: Jupiter — yes.

All good.

Final Answer:
1. Jupiter
2. Saturn
3. Venus
4. Mars
5. Uranus
6. Pluto
7. Mercury
8. Neptune
9. Earth
