Buddhism: What is the difference between Nirvana, Moksha, and Enlightenment?

They are all connected. I know Moksha is liberation from Samsara. Enlightenment is knowing the answers and leads to Nirvana? Nirvana is like what this blissful god-like state of being where you have no more suffering and will not be reborn again? Can Moksha be achieved without attaining the other 2? Does that end a person in Nirvana after they die? I am confused. Explanations would be really appreciated. Thank you.
