The Solar System, Explained
A friendly tour of the planets, moons and the star at the middle of it all.
Which planet is closest to the Sun?
The universe, the atom, and every living thing in between.
Science and nature is where curiosity starts for most of us, and it is still the broadest corner of QuizKite. These quizzes move from the very large to the very small: the planets and the forces that hold them in orbit, the chemistry of the elements everything is built from, the weather over your head, and the workings of the body you carry around all day. Some of it you half-remember from school; a lot of it is stranger and more recent than school let on. The point is not to catch you out on obscure trivia, but to reconnect the everyday things you already notice with the reasons behind them. Why is Venus hotter than Mercury? Why does the moon look so large near the horizon? Each quiz picks a slice of the natural world, asks about the parts worth knowing, and explains the answer so it sticks.
