Correct sentence: The largest planet in our Solar System is Jupiter, and the smallest is Mercury.
Nice try! Here are three simple tips to remember:
- Use normal capital letters: Planet names start with one capital letter, like Jupiter and Mercury.
- Don't use ALL CAPS. Writing everything in big letters is hard to read.
- End the sentence with a period.
If you want to say it in two short sentences, you can write:
- Jupiter is the biggest planet in our Solar System.
- Mercury is the smallest planet in our Solar System.
Great work — keep practicing!
