Solar System Knowledge Assessment

The video explores our solar system, one of over 500 in the Milky Way. It formed 4.5 billion years ago from a collapsing interstellar cloud. The solar system is in the Orion star cluster, with only 15% of stars hosting planets. Our sun has eight planets, divided into terrestrial (rocky) and Jovian (gas and ice giants) categories. Terrestrial planets include Mercury, Venus, Earth, and Mars, while Jovian planets are Jupiter, Saturn, Uranus, and Neptune. The asteroid belt lies between terrestrial planets, and the Kuiper belt and Oort cloud are beyond the Jovian planets. The solar system's configuration supports life on Earth, making it unique.
