Will the sun eventually become a planetary nebula?

Well, sweet cheeks, the sun won't become a planetary nebula. As a middle-aged star, the sun will actually shed its outer layers to form a planetary nebula, revealing its hot core known as a white dwarf. So, technically, the sun won't become a planetary nebula, it'll just pull off a fabulous costume change in the cosmic dance of the universe. Hope that clears things up for ya!
