Origin

The Sun's full name is just the Sun. Modern English sun evolved from the same Proto-Germanic form that today is Sonne in German and zon in Dutch, variously attested as sonne and sunne in Old and Middle English, with similar forms found in other ancient Germanic languages such as Old Norse, Old Saxon, Old High German and Gothic.

The Sun formed 4.6 billion years ago from a vast cloud of gas and dust called the Solar Nebula. Over millions of years, this gas and dust collected into the Sun and the planets. Once the Sun’s gravity compressed its hydrogen enough, temperatures in the core reached the point of igniting solar fusion, releasing the energy we feel here on Earth.
