SOLAR SYSTEM

Detailed explanation-1: -Most of the nebula’s material was pulled toward the center to form our Sun, which accounts for 99.8% of our solar system’s mass. Much of the remaining material formed the planets and other objects that now orbit the Sun. (The rest of the leftover gas and dust was blown away by the young Sun’s early solar wind.)

Detailed explanation-2: -The explosion would be so powerful that planets such as Mercury, Venus, Earth, and Mars would be completely destroyed. However, all living things on Earth would die before the explosion’s light, debris, or shockwaves would reach us.

Detailed explanation-3: -Over time, dust gets removed from ring systems due to a variety of processes. For example, some of the dust falls into the planet’s atmosphere, while some gets swept up by the planet’s magnetic fields, and other dust settles onto the surfaces of the moons and other ring particles.

Detailed explanation-4: -Comets are frozen leftovers from the formation of the solar system composed of dust, rock, and ices. They range from a few miles to tens of miles wide, but as they orbit closer to the Sun, they heat up and spew gases and dust into a glowing head that can be larger than a planet.
