Sun’s Rotation
Sun rotates once on its own axis after 27 earth days.
How long will the sun continue to shine?
You may think that sun will die soon because it is an aged star now. However, there are estimates regarding this assumption according to which the sun has capability to shine for another 5 billion years.
Time Light Takes to Reach the Earth
It takes light 8 minutes to reach earth from the sun.
Largest Supplier of Energy
Astrophysicist believed that almost all energy provided to earth is by sun. No doubt it is the center of solar system.
Elements in the Sun
Though the sun is 74 percent hydrogen and 24 percent helium but the sun contain other elements also like carbon, neon, oxygen, iron.
Stars bigger than Sun
Isn’t it surprising? There are many stars in galaxy that are bigger and brighter than the sun. But we cannot see them because they are far away from Earth.

There are eight planets in our solar system. However, as a kid many of us had studied that there are nine planets but Pluto is a small planet which is now classified as Dwarf Planet.
Symmetry of Solar Eclipse
Have you ever wondered why the symmetry of solar eclipse is so perfect? It is because the sun is 400 times bigger and also 400 times farther from the moon. Due to which the shape of eclipse seems perfect.
Layers of Sun
There are seven layers of sun. The three inner layers core, Radiative zone, Convection zone while the outer layers are photosphere, Chromosphere, transition region and corona.
Who discovered it
Well, life exists just because of sun. There is no specific date for its discovery. It sounds weird also because life didn’t exists before its formation. It is always there so no one needed to discover it. However, other planets in solar system have specific discovery dates.
State of Matter
Are you curious to know the state of matter present in the sun. All this matter is in gaseous state, mostly plasma.
Speed of Rotation
The speed of rotation of sun varies from equator to pole. It rotates fastest at the equator and the speed is comparatively slow on the poles.
Atmosphere of Sun
There are three areas that constitute the atmosphere of sun. These are solar corona, Chromosphere, and Photosphere.
How Sunlight is produced?
In our science books we have read that there are four types of nuclear reactions e.g. Fusion, Fission, Nuclear decay and transmutation. Sunlight is produced as a result of fusion nuclear reactions taking pace in the sun. Firstly gamma rays are formed as product of reaction, which on billions of collision with matter reaches the surface of sun. Thus escape into the space.
How hot is the Corona of the Sun
The outer atmosphere of sun is known as Corona. There the temperature can extend from thousand to million kelvins.
Sun emit two types of Radiations
Sun emit particle radiations like electron, alpha particles, protons etc. and electromagnetic radiations (which are photons).
Life of Massive Stars
The more massive a star is the sooner it will die. Short stars tend to have long life. Massive star die soon because the rate at which it burns its fuel is higher.
Visible Part
What we see from Earth is the visible part of Sun known as photosphere.
Sunspots
No we are not talking about the one that appear on our skin due to exposure to sunlight. The sun has sunspots on its surface. These spots are formed by sun’s magnetic field emitting its surface. These areas become cooler and dark. Scientist named these areas as sunspots.
Hottest part of Sun
Core is the blazing hot part of sun. The temperature in the core is 28, 080, 000 degrees Fahrenheit. That’s pretty hot.
Sun God
Ancient Egyptians used to worship sun god called Ra.
Tonatiuh God
Aztecs civilization belonging to America used to offer human sacrifices to sun god called Tonatiuh. They thought that sun would not shine if they stop offering sacrifices.
Sol Invictus
Roman worshipped sun god named Sol Invictus.
Greek’s Sun God
Greek’s used to call sun as Helios.
Looking at Sun
Don’t look at the sun directly because it can damage your eyes permanently.
Solar Wind
Sun not only emit light and heat but also emit streams of charged particles which are named as solar wind.
Moon’s light is actually due to reflection
Only stars emit light while other bodies in space doesn’t give light. Similarly moon’s light is actually the reflection of sunlight from its surface.
Sun move across the sky
The ancients believe that the sun rises in the east move across the sky and the sets in the west. They didn’t know that this phenomena is due to the rotation of earth on its own axis.
Radiative Zone of Sun
The core of sun is surrounded by the radiative zone. The energy produced by the core is transported by the radiative zone.
Corona Atmosphere is Visible Sometimes
There are two possible scenario where we can see corona of sun clearly. One in misty weather conditions and the other during solar eclipse.
Stonehenge used to worship Sun
Many people believed that Stonehenge were used to worship the sun.

Aristarchus was an ancient Greek astronomer. At that time people believed that sun rotates around the earth. But Aristarchus first time explained that Earth rotate around the sun.
Shape of Sun
The shape of sun is close to a perfect sphere.
Chromosphere is much hotter than sun’s surface
Well, it is hard to believe that the surface of sun is less hot than chromosphere (atmosphere above the sun’s surface). The temperature can reach to 100,000 kelvins at the surface while in chromosphere it is 1 million kelvins.
Tattoos of the Sun
The ancient mummies of male and female found in Libya have tattoos of the sun on their bodies. This shows that they either worshiped the sun or their civilization used to praise the sun very much.

OMG, you will be shocked to know the weight of the sun. It is a huge number-4,385,214,857,119,399,823,317,774,893,056 pounds.
Sun will eat the Earth
According to scientist, once all the hydrogen on the sun would burn up. The sun will engulf the Earth, Mercury, and Venus. After consuming these planets it will become a red giant ball.
Theory of Gravity helped understanding Solar System
Sir Isaac Newton presented the theory of gravity. Before this theory there were many confusions regarding the solar system.
Sun Sound
Yes! That’s right. Sun produce a specific sound waves. The wavelength of these sound waves is very short.
Coronagraph
A telescope especially designed to observe corona surrounding the sun is called Coronagraph. The lens of the telescope block the sun rays without which it becomes easy to study things related to the sun.
