How many planets make up the solar system?

Answer 1

There are currently eighteen known planets and two protoplanets in our solar system. We are always discovering more, so this may change. This is also widely debated, because different scientists think differently about how "planet" should be classified. It is common for scientists to only acknowledge eight planets in our system, and it is true that there are eight main planets. However, there are also ten dwarf planets, which are a form of small rocky planet.
