Step-by-step solution for: Our Solar System Worksheets | Worsheets library
Let's solve the "Planet Facts" worksheet step by step. The task is to match each planet (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune) with its correct description from the list on the right.
---
Planets:
- Mercury
- Venus
- Earth
- Mars
- Jupiter
- Saturn
- Uranus
- Neptune
Descriptions:
1. The largest planet in our solar system
2. The smallest planet in our solar system
3. Where we live
4. The hottest planet
5. Has seven rings and at least 60 moons
6. The windiest planet with winds up to 1,200 mph
7. Known as the "red planet"
8. An "ice giant" that spins on its side

Let’s go one by one using known facts about the planets:
#### ✔ Mercury
- Smallest planet in the solar system.
- Also has the largest temperature variation, but not the hottest.
- Match: *"The smallest planet in our solar system"* → #2
#### ✔ Venus
- Hottest planet due to extreme greenhouse effect (surface temp ~470°C).
- Not the smallest or largest.
- Match: *"The hottest planet"* → #4
#### ✔ Earth
- Our home planet.
- Match: *"Where we live"* → #3
#### ✔ Mars
- Reddish appearance due to iron oxide (rust) on surface.
- Called the "Red Planet".
- Match: *"Known as the 'red planet'"* → #7
#### ✔ Jupiter
- Largest planet in the solar system (gas giant).
- More than twice the mass of all other planets combined.
- Match: *"The largest planet in our solar system"* → #1
#### ✔ Saturn
- Famous for its rings (though it has many small rings, not just 7 — but some sources say 7 main ones).
- Has over 80 moons, so “at least 60” is accurate.
- Match: *"Has seven rings and at least 60 moons"* → #5
> Note: While Saturn has more than 7 rings, this is a simplified version often used in grade-level worksheets.
#### ✔ Uranus
- Spins on its side (tilt of ~98 degrees), so it rotates almost horizontally.
- Classified as an ice giant (along with Neptune).
- Match: *"An 'ice giant' that spins on its side"* → #8
#### ✔ Neptune
- Extremely windy planet; winds up to 1,200 mph (fastest in the solar system).
- Also an ice giant.
- Match: *"The windiest planet with winds up to 1,200 mph"* → #6
