Formation. Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova. When this dust cloud collapsed, it formed a solar nebula—a spinning, swirling disk of material. Approximately 4.6 billion years ago, the solar system was a cloud of dust and gas known as a solar nebula. Gravity collapsed the material in on itself as it began to spin, forming the sun in the center of the nebula. With the rise of the sun, the remaining material began to clump together. Part of Hall of the Universe. The Sun and the planets formed together, 4.6 billion years ago, from a cloud of gas and dust called the solar nebula. A shock wave from a nearby supernova explosion probably initiated the collapse of the solar nebula. ... In a similar manner, moons formed orbiting the gas giant planets. Hope this helps!

Answer:
Alternative Name: The Killer Fog of 1952
Great Smog of London, lethal smog that covered the city of London for five days (December 5–9) in 1952, caused by a combination of industrial pollution and high-pressure weather conditions. This combination of smoke and fog brought the city to a near standstill and resulted in thousands of deaths. Its consequences prompted the passing of the Clean Air Act four years later, which marked a turning point in the history of environmentalism.
The phenomenon of “London fog” long predated the crisis of the early 1950s. Known as “pea-soupers” for their dense, yellow appearance, such all-encompassing fogs had became a hallmark of London by the 19th century. But polluted fog was an issue in London as early as the 13th century, due to the burning of coal, and the situation only worsened as the city continued to expand. Complaints about smoke and pollution increased in the 1600s, when ultimately ineffective legislation was passed under King James I to restrict coal burning. Rapidly increasing industrialization that began in the late 1700s made conditions even worse.
These hazes were not natural formations of the atmosphere: water vapour would stick to particulates released by coal-burning factories, producing dark and heavy clouds that impaired visibility. This variety of fog later came to be known as smog (a merging of the words smoke and fog), a term invented by a Londoner in the early 20th century.
