<h3>What is a solar nebula?</h3>
A molecular cloud, a collection of interstellar dust and hydrogen gas, is where our solar system first formed. Our proto-Sun originated in the hot, dense center of the cloud as it shrank due to its own gravity. The solar nebula, made up of the remaining cloud, is a whirling disk.
The Solar Nebula spun faster and faster before flattening into our solar system's rotating disk in the following order: The Sun was formed when the majority of the gas was drawn into the core, where it heated up and became dense.
After extensive study, astronomers now believe that the Milky Way galaxy contains more than 100 billion stars, including the Sun. It was created 4.6 billion years ago and has a diameter that is 109 times that of the Earth. The Sun has a surface temperature of 10,000 degrees Fahrenheit and a core temperature of 27 million degrees Fahrenheit.
