The Sun is one of many billions of stars in the Milky Way. The Sun emits a very large quantity of energy as electromagnetic radiation. State the three regions of the electromagnetic spectrum in which the Sun emits the most energy. Electromagnetic radiation from the Sun travels at a speed of 3.0 × 108 m / s. The radiation takes 500 s to reach the Earth. Calculate the distance from the Sun to the Earth. distance = Approximately 4.6 billion years ago, the Sun formed from an interstellar cloud of gas and became a stable star. Describe and explain what happens as an interstellar cloud of gas forms a protostar. Describe and explain what happens as a protostar becomes a stable star.
