The Sun is the only star in our solar system around which all other space objects orbit. The mass of our star is 99.866% of the total mass of the solar system, and the radiation from the Sun supports the life of all flora and fauna on planet Earth. About this and much more will tell you curious facts about the Sun.
1. The Sun is a relatively young third-generation star, which was formed from the remains of first- and second-generation stars. This explains the high metal content of the Sun.
2. Scientists estimate the age of the Sun at 4.57 billion years. Scientists believe that a star of such mass must live for about 10 billion years. The Sun is in the middle of its life cycle.
3. The Sun is the fourth brightest star among the 50 nearest star systems within 17 light years.
4. The Sun revolves around the center of our galaxy, the Milky Way, from which it is 26,000 light years away. Full rotation of the Sun makes over 200 million years. Light year the Sun passes in 1400 Earth years, which is about 217 kilometers per second.
5. In about 4-5 billion years, the Sun will become a red giant star. The Sun is now spectrally classified as G2V, which means “yellow dwarf.
6. The Sun burns 700 billion tons of hydrogen every second.
7. Every year there are at least two solar eclipses. And once every 300 years, there is a total eclipse of the Sun, which lasts for a brief time.
8. The Sun is about 109 times larger than the Earth in diameter.
9. In 8 minutes, the sunlight travels 150 million kilometers. This is about the distance from the Sun to the Earth.
10. Parhelion is a phenomenon caused by the refraction of sunlight in ice crystals floating in the atmosphere. Several false light sources can be seen in the sky in this case. This rare phenomenon in history has become a herald of important events. So, in “The Tale of Igor’s Campaign” described the appearance of four suns in the sky, which was a harbinger of polovtsy attacks. And during the major battle in England between Lancaster and York, three suns appeared in the sky, which King Edward IV interpreted as a personification of the Holy Trinity.
