7 unexpected facts about the Sun.

The Sun lies very far from Earth, making light need about 8 minutes 19 seconds to reach the Earth and a plane must fly for 26 years to reach the central star of the solar system.

1. Huge size

In fact, the large size of the sun can hold about one million Earths inside. The weight of the sun accounts for about 99.8% of the solar system's total mass, 330,000 times the total mass on Earth.

2. Great energy

The surface temperature of the Sun is about 5,537 degrees Celsius, while the temperature inside the Sun's core is about 15 million degrees Celsius. The energy generated from the Sun's core essentially releases heat and light. The light that we often get from Earth. It is estimated that the energy generated from the Sun is equivalent to the energy when it detonates 100 billion tons of explosives.

3. Not Copernicus suggests that the Sun is the center of the solar system

Astronomer Nicolas Copernicus is not the first to suggest that the Sun is the center of the solar system as everyone knows. In fact, the Greek astronomer Aristarchus of Samos was considered the first person to propose a model called Japanese mind around the 3rd century BC, nearly 1,800 years before Copernicus's assertion.

4. Located very far from Earth

The Sun lies about 150 million kilometers from Earth. With this great distance, light needs about 8 minutes 19 seconds to reach the Earth. According to the calculations of scientists working at NASA American Aerospace Agency, a plane must fly for 26 years to reach the Sun.

5. Great gravity

When on the "fireball", a person weighing an average of 68 kg above the Earth will weigh about 1,900 kg. This is explained by scientists because the Sun has 28 times the gravitational force of gravity on our planet.

6. The Sun is "old"

So far, the Sun is estimated to be 4.6 billion years old and is going through the last 5 billion years before it starts burning helium, becoming a giant red star and will swallow Venus, Mercury, maybe the whole Earth. After about 1 billion years as a red star, the Sun will shrink into a white dwarf.

7. Reverse polarity

When the maximum energy level is reached or the maximum active phase, the Sun's magnetic field reverses the polarization direction, which is essentially the opposite of the north and south. Scientists say the Sun will reverse polarity about every 11 years and has observed a reversal that began in August this year.
