Stephanie & Isabella's Solar System

The Sun is one out of billions of stars. The Sun is the closest star to Earth. The Sun rotates once every 27 days. The Sun is now a middle-aged star, meaning it is at about the middle of its life. The Sun formed over four and a half billion years ago. You may think the Sun will die soon, but it will keep shining for at least another five billion years. The Sun’s surface is called the photosphere. The temperature of the photosphere is about 10,000 Fahrenheit. Its core is under its atmosphere. The temperature at the core, or very middle, of the Sun, is about 27 million Fahrenheit.
