The second biggest planet in our solar system is Saturn. It is important to note that as an AI, I don't have real-time data, so it's always a good idea to double-check information like this. But generally, the easiest way to find the answer to this question is by using an internet search engine. Simply type in "second biggest planet in our solar system" and you should quickly find the answer. Another option is to refer to science books or educational websites that provide information about the planets in our solar system. These sources typically include details about the size and order of the planets.
