The solar system is the beginning of all the eras. 4.6 billion years ago, a gas explosion led to the formation of the solar system. without the solar system, there would have been no concept of the universe and planets, no life, no sun or science.
The solar system is where it all began. And even now the solar system and whole universe keep giving us new insights and knowledge that we did not know before. The asteroids, milky way, galaxy, and orbit are also part of the solar system that is responsible for new changes every day.
Most asked questions on solar system
The solar system is a vast concept to grasp and comprehend. Scientists to date keep an eye on outer space noticing slight changes every day. So, naturally, children to elders, all have some or other questions about the solar system, sun, asteroids, moon and planets. In the following phase of this article, some of these most asked questions will be addressed and answered.
How long does it take sunlight to reach planet earth?
It takes about 8.3 minutes for the sunlight to enter the planet earth after the sun has emitted the sun rays. Mercury, which is the closest planet to the sun, gets sunlight in 3 minutes. And Neptune, being the farthest planet, gets sunlight in about 4.15 hours. The sun’s reach is up till infinity and there is no limit as to where the sunlight can reach last. The sun’s radius is so big that it is estimated that at least 1.12 million piles of earth can fit inside.
Can asteroids hit the sun?
According to all the news and facts, an asteroid is never seen to hit the sun. There has been no prior evidence of an asteroid on the surface of the sun up till now, but that does not mean it cannot. There is no sign or scientific fact that tells about the impossibility of asteroids hitting the sun.
The asteroids are generally in the asteroid belt between Mars and Jupiter, but sometimes they do enter the inner part of the solar system. Although the asteroids have many times fallen in the direction of the sun, they never hit the surface. And there is a scientific explanation behind this – angular momentum. An object with angular momentum in its movement can never fall into or hit on the surface of the sun.
Is the sun a star?
The first invention of calling the sun a star was made by Anaxagoras in 450 BC, and later scientifically proved by Galileo, Kepler, Newton, and Fredrich Bessel. The sun is called a star because of the following reasons –
- The sun uses 600 million tonnes of hydrogen which helps it to turn 4 million tonnes into energy.
- This energy is the reason why the sun can produce unlimited heat and light
- The sun’s uncontrolled energy and power are expected to blow the sun up someday when the sun will expand its outer layers and eventually expand.
Is NASA important?
The National Aeronautics and Space Administration (NASA), holds one of the most important roles in studying the solar system. This particular representative body of scientists observes aeronautics, space, universe, technology, planets, asteroids. Asteroids earth NASA observes the asteroids’ movements in the surrounding space of the planet.
What is the sun made of?
We all know that the sun is a giant ball of fire that produces light, heat and life on earth. But how often do we wonder what it is made of? The sun is made with 70% hydrogen, 28% helium, 1.5% carbon, nitrogen and oxygen, and 0.5% of substances such as nickel, and iron.
Conclusion
Thus, the solar system remains a curious and interesting subject. It will take every life on earth before we discover and know everything about the solar system and its secrets. From life to asteroids and planets we all depend on the universe and solar system to know more and deeper.
