"Earth is one of eight planets in our solar system"
If you wanted to express that Earth is one of the planets of the Solar System, you could say either of the following: "Earth is one of the planets of the Solar System" or "Earth is one of eight planets in our solar system". Both of these expressions express this fact.
「地球は太陽系の惑星の一つです」は次のように言えます。
"Earth is one of the planets of the Solar System"（地球は太陽系の惑星の一つです）
"Earth is one of eight planets in our solar system"（地球は太陽系に八つある惑星のうちの一つです）
どちらの表現もこの事実について伝えています。
Earth is one of the 8 major planets in the Solar System.
I use the phrase "major planet" because there are thousands of planets within the Solar System but there are only eight important planets, which are the ones that we learn in school. The names "Earth" and "Solar System" should be capitalized because they are proper nouns. I hope that this helps. :)
