Educational worksheet matching planet descriptions to their correct names and images.

Here is the solution to the "Solar System Match Up" worksheet, with a clear explanation for each match:

---

1. The largest planet in the solar system. → Jupiter

* Explanation: Jupiter is a gas giant and by far the largest planet in our solar system. Its mass is more than twice that of all the other planets combined. In the image, it’s the large brownish planet with prominent bands.

2. The sixth planet from the sun in the solar system. → Saturn

* Explanation: Counting outward from the Sun: 1. Mercury, 2. Venus, 3. Earth, 4. Mars, 5. Jupiter, 6. Saturn. Saturn is famously known for its spectacular ring system, which is clearly depicted in the image.

3. The brightest planet in the solar system. → Venus

* Explanation: Venus appears brighter than any other planet in our night sky (except the Moon) because it is relatively close to Earth and has a highly reflective cloud cover. It’s often called the “Evening Star” or “Morning Star.” In the image, it’s the orange-yellow planet with subtle cloud bands.

4. The planet with the nickname “Red Planet”. → Mars

* Explanation: Mars is called the “Red Planet” due to the iron oxide (rust) on its surface, giving it a distinct reddish-orange appearance. The image shows a clearly red planet.

5. The coldest planet in the solar system. → Neptune

* Explanation: While Uranus can sometimes have lower recorded temperatures, Neptune is generally considered the coldest planet on average because it is the farthest from the Sun (since Pluto is no longer classified as a planet). Neptune’s deep blue color in the image reflects its cold, methane-rich atmosphere.

6. A dwarf planet in the solar system. → Pluto

* Explanation: In 2006, the International Astronomical Union reclassified Pluto as a “dwarf planet” because it hasn’t cleared its orbital neighborhood of other objects. It is shown in the image as a small, grayish sphere with darker patches.

7. The planet closest to the sun in the solar system. → Mercury

* Explanation: Mercury orbits closest to the Sun. It’s also the smallest planet in our solar system. The image shows a small, cratered, yellowish planet — matching Mercury’s rocky, airless surface.

8. The planet farthest from the sun in the solar system. → Neptune

* Explanation: Since Pluto is now a dwarf planet, Neptune is the eighth and farthest *planet* from the Sun. This matches description #5 as well — Neptune is both the farthest planet and the coldest (on average).

9. The only known planet to support life. → Earth

* Explanation: Earth is unique in our solar system (and so far, the universe) for having conditions suitable for life as we know it — liquid water, an atmosphere, and a temperate climate. The image shows the familiar blue and green globe.

✔ Final Answer Key:

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

*(Note: Neptune is matched to two descriptions — #5 and #8 — which is correct based on current scientific understanding.)*
