why do the planets orbit the sun

[/caption] In ancient times, astronomers thought that all celestial bodies – the Sun, Moon, planets, and stars – orbited the Earth in a chain of crystal balls. But as modern science develops, astronomers can better understand our place in the universe. They found that all the planets, including Earth, actually orbit the Sun. What sequence of events led us to the present Solar System, with the planets orbiting the Sun? Astronomers used to think the Earth was the center of the Solar System Because we live on Earth, and we see objects pass our vision in the sky, it is natural to assume that Earth is the center of the Universe. In fact, this view – known as geocentrism – was held by all ancient civilizations. The Sun, Moon, planets and stars seem to move around the Earth every day. And because the Earth itself does not appear to be moving, astronomers like Ptolemy suggest that the Earth is the center of the Universe. In fact, they went as far as to create highly detailed models to predict the motions of objects with great accuracy, using this completely imprecise model of the Solar System. Ptolemy’s predictions were used to make astrological predictions for over 1500 years, until a much better model came along.In fact, the Sun is the Center of the Solar System A new, more accurate model of the Solar System did not emerge until the 16th century, when Polish astronomer Nicolai Copernicus published his book Changing the Universe: On the Revolutions of the Celests body. Copernicus precisely reorganized the Solar System, placing the Sun at the center in a heliocentric model. And Earth took its rightful place, just another planet orbiting the Sun – one of only six that astronomers knew at the time. for several months (as they get closer and closer), and why the planets seem to reverse and move in the direction of retrograde. Easily explained because of the changing position of the Earth, planets and background stars. Read more: Why did muzan turn nezuko into a demonBut why do they orbit the sun? Once they were able to accurately describe the nature of planetary motion in the Solar System, they were left with only one more fundamental question: Why do planets orbit the Sun? What sequence of events led to the current motion of the planets around the Sun? To explain this, we need to look back to 4.6 billion years ago, before the entire Solar System existed. Instead, in our place, there is a huge cloud of hydrogen gas left over from the Big Bang. Some event, such as a nearby supernova explosion, caused the cloud’s gravitational collapse, causing the hydrogen atoms to stick together through mutual gravity. of gases, the conservation of momentum on all particles causes these gas clusters to rotate. Imagine two skydivers spinning in midair colliding with each other; After the collision, they will have a new speed and direction of rotation based on the addition of their original directions. As it collapsed, it started spinning faster and faster, like a figure skater pulling in her hand increasing her spin. a plate of pancake-shaped material surrounds it. Planets form from this disk of matter, gathering dust particles into increasingly larger rocks until planet-sized objects accumulate together. Top Q&AThe planets are in perfect equilibriumThe planets orbit the Sun because they are left over from the formation of the Solar System. Their current motion depends on the gravitational pull of the Sun at the center of the Solar System. In fact, they are in perfect equilibrium. If gravity prevailed, the planets would twist inward. If their inertia prevailed, the planets would spiral out into deep space.More research: Cornell astronomy The universe by Aristotle and Ptolemy Isosomes model: Solar system centered on the Sun Solar nebula On the revolution of the celestial bodies Copernican revolution Read more: why are alkenes so much substituted more stable | Top Q&A
