SOLAR SYSTEM

Detailed explanation-1: -Sunspots are areas that appear dark on the surface of the Sun. They appear dark because they are cooler than other parts of the Sun’s surface. The temperature of a sunspot is still very hot though-around 6, 500 degrees Fahrenheit!

Detailed explanation-2: -The sunspots appear relatively dark because the surrounding surface of the Sun (the photosphere) is about 10, 000 degrees F., while the umbra is about 6, 300 degrees F. Sunspots are quite large as an average size is about the same size as the Earth.

Detailed explanation-3: -Sunspots appear dark because they are cooler than their surroundings. Large sunspots are thousands of degrees cooler than the areas that surround them (about 4, 200 °C for a sunspot compared to 6, 000 °C for the photosphere surrounding it). Sunspots are only dark in contrast to the bright face of the Sun.

Detailed explanation-4: -The cooler areas on the surface of the sun are called sunspots. They are seen as black spots on the surface of the sun and are relatively low-temperature regions in comparison with the brighter and hotter regions of the photosphere around them.

Detailed explanation-5: -Sunspots are phenomena on the Sun’s photosphere that appear as temporary spots that are darker than the surrounding areas. They are regions of reduced surface temperature caused by concentrations of magnetic flux that inhibit convection.
