What Is The Sun?

The sun is the star at the center of our solar system and is responsible for the Earth's climate and weather. It is a nearly perfect sphere of hot plasma, with internal convective motion that generates a magnetic field via a dynamo process. Its diameter is about 1.39 million kilometers (864,000 miles), and its mass is about 330,000 times that of Earth. It accounts for about 99.86% of the total mass of the Solar System.

What Color Is The Sun?

The sun is actually a white star and appears yellow, orange, or red in the sky because of the combination of gases and particles in Earth's atmosphere. Although the sun is classified as a white star, it actually emits all colors of light and is considered a broad spectrum source. Scientists measure the sun's spectrum to understand how it affects the Earth's climate, atmosphere, and environment.

Why Does The Sun Appear Yellow or Orange?

The sun's light is composed of all the colors of the rainbow, including red, orange, yellow, green, blue, indigo, and violet. However, the atmosphere of Earth scatters some of the colors more than others, which makes the sun appear more yellow or orange. This is because the atmosphere scatters the higher energy blue and violet light more than the lower energy red and orange light. This is why the sun appears yellow or orange in the sky.

What Is The Sun's Temperature?

The sun's temperature is incredibly hot. The surface of the sun is around 5,778 degrees Kelvin (5,505 degrees Celsius, 9,941 degrees Fahrenheit). This is much hotter than the temperature on Earth, which is typically around 15 degrees Celsius (59 degrees Fahrenheit). The sun's core is even hotter, estimated to be around 15 million degrees Celsius (27 million degrees Fahrenheit).

Conclusion

The sun is a white star that appears yellow, orange, or red in the sky because of the combination of gases and particles in Earth's atmosphere. The sun emits all colors of light, but the atmosphere scatters the higher energy blue and violet light more than the lower energy red and orange light, which is why the sun appears yellow or orange in the sky. The sun's temperature is incredibly hot, with a surface temperature around 5,778 degrees Kelvin (5,505 degrees Celsius, 9,941 degrees Fahrenheit).
