Sun
Important details about the sun
* The age of sunlight is about 5 billion years.
* Chemical composition: Hydrogen is 71%, helium is 26.5% and other elements are 2.5%.
The time it takes for the sun’s rays to reach the earth
* It takes 8 minutes (7.56 minutes) for the sun’s rays to reach the earth.
The mass of the sun
* The mass of the Sunlight is about 740 times the mass of all the planets. This is 3,00,000 times the mass of the Earth.
Diameter of the sun
* The diameter of the Sun is 13,92,000.Km.Light ambient temperature: 6000 degrees centigrade.Ambient temperature: 1,00,000 degrees centigrade.Central zone temperature: about 15 million degrees Kelvin.
The time it takes for the sun to revolve around the solar system
* The time it takes for the sunlight to revolve around the solar system is 250 million years.
Excess gases in the sun
* The most abundant gases in the sunlight are 90% hydrogen, 8% helium, and 2% other elements.
* The closest star to Earth after the Sunlight is Pragjima Centauri, and the time it takes for light to reach Earth from Pragjima Centauri is about 4.3 light-years. The nearest star to the Sunlight is named Alpha Centauri.
* The average distance between the Earth and the Sun is 149.5 million, also known as an astronomical unit. The distance between the sunlight and the earth is greater The context is called the apocalypse. It usually occurs on July 4th. Then the distance between the earth and the sunlight is 152 kilometers as well as the distance between the sun and the earth The lesser context is called the Parihelian. It usually occurs on January 3rd. Then the distance between them is about 147 m. K. Mr.
How many planets revolve around the sun?
8 planets are orbiting the sun. They are:
1. Mercury
2. Venus
3. Earth
4. Mars
5. Jupiter
6. Sat.
7. Varun
8. Indra
These eight planets can be divided into two categories. They are 1. Interplanetary 2. External planets
* The first four planets are called interplanetary. They are usually small in size and high in density, with a high gravitational pull on the Sunlight. These are high Have temperatures.
* The last four planets, Jupiter, Saturn, Varuna, and Indra, are called external planets. These are large in size and low in density. The gravitational force of the sunlight is less on these. These are to the sunlight Low temperatures are recorded on these due to their extreme distance.
