Here are two simple ways to say the same thing:
Way 1: Out of all the planets that go around the Sun, Jupiter is the biggest and Mercury is the smallest.
Way 2: Jupiter is huge — it is the largest planet in our Solar System. Mercury is tiny — it is the smallest planet.
Short steps to make these rephrases:
- Find the two facts: Jupiter = biggest, Mercury = smallest.
- Pick easy words a 7-year-old knows (biggest / largest, smallest / tiny).
- Put the facts into short, clear sentences and mention the Solar System (the Sun and the planets that go around it).
Tip: You can say "biggest" or "largest," and "smallest" or "tiniest" — they mean the same thing for planets.
