8. How many planets does the Solar System have?
We all know that Pluto or Pluton was kicked out of the Solar System in 2006. Also, we are aware of the fact that there are 8 planets which are gravitating around the sun.
In addition to that, we can say that the vast majority of our Solar System is still uncharted and unknown by scientists.
Actually, the area between the Sun and Mercury is too bright to see what’s truly there, while the area that is beyond Uranus is too dark. Scientists are still finding new objects in space, so maybe there are planets that exist, but we don’t know about them.
