Characteristics of the Sun

The Sun is the nearest star to the Earth The Sun is the nearest star to the Earth. It is made up of very hot gases with the center of the Sun measuring about 15 million °C!!!

The Sun is the only star in our solar system The Sun is the only star in our solar system. The stars that we see in the night sky are much farther away in other solar systems.

The Sun is a yellow dwarf star.

Photosphere is the name given to the surface of the Sun.

photosphere

Sunspots are dark spots on the surface of the Sun where the temperature is lower than the surrounding areas.

The chromosphere lies just outside the photosphere and is almost transparent. It is seen as a red glow around the Sun.

The corona is the outermost layer of gases surrounding the Sun The corona is the outermost layer of gases surrounding the Sun. It can only be seen during a solar eclipse.

What are sunspots and where are they found?

Sunspots are dark spots on the surface of the Sun (photosphere) where the temperature is lower than the surrounding areas.

When can we see the corona on the Earth?

We can only see the corona during a solar eclipse.

Which layer can be seen as a red glow around the Sun and is almost transparent?

The chromosphere is seen as a red glow around the Sun and almost transparent.
