The Most Epic Space Missions Humanity Has Known

The approximate radius of the solar system is 30 trillion kilometers. During the whole time of exploration of this space, mankind has found 316 minor planets.

And 8 main ones that everyone knows about. But “know” is too big a word. In most cases, we only know what these planets look like and at what distance they are from the Earth.

Everything else is just our assumptions. To replace speculation with facts, humanity regularly sends space research probes to other planets.
