Question #7 - How many things are there in the solar system?

The Solar System. Start counting!
When I was at school the solar system consisted of the sun and 9 planets. The third planet had a moon, so that was 11 things. And if that was it, this would be so much easier, but it's not. There aren't even 9 planets any more, there are 8. The ninth planet was demoted to dwarf planet status and several other dwarf planets have been discovered since then. There are comets, asteroids, moons/satellites and of course the things that we have put out there.
