FAQs on Solar System Video Lecture - Crash course for UPSC (Hindi)
| 1. What is the Solar System? |  |
Ans. The Solar System is the collection of planets, moons, asteroids, comets, and other celestial bodies that orbit around the Sun. It is located in the Milky Way galaxy and consists of eight planets, including Earth, and their respective moons, as well as smaller objects like asteroids and comets.
| 2. How was the Solar System formed? | |
Ans. The Solar System formed approximately 4.6 billion years ago from a giant molecular cloud composed mostly of hydrogen and helium. The cloud collapsed under its own gravity, giving rise to a rotating disk of gas and dust called the protoplanetary disk. Within this disk, particles collided and gradually formed larger objects, eventually leading to the formation of the Sun at the center and the planets, moons, and other objects around it.
| 3. What are the eight planets in the Solar System? | |
Ans. The eight planets in the Solar System, in order of their distance from the Sun, are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. These planets vary in size, composition, and atmospheric conditions, with Earth being the only known planet to support life.
| 4. What are some notable features of the Solar System? | |
Ans. The Solar System is home to several notable features. One of the most prominent is the asteroid belt, located between the orbits of Mars and Jupiter, which contains numerous rocky objects. Another feature is the Kuiper Belt, a region beyond Neptune's orbit that is home to icy bodies such as Pluto and other dwarf planets. Additionally, the Solar System includes various moons, such as Earth's Moon, Jupiter's Ganymede, and Saturn's Titan.
| 5. How does the Solar System affect Earth? | |
Ans. The Solar System plays a crucial role in shaping the conditions on Earth. The gravitational pull of the Sun keeps our planet in orbit and provides the necessary conditions for life to exist. The Sun's energy, in the form of sunlight, drives Earth's climate and supports photosynthesis, which is essential for the production of oxygen and food. Additionally, the interactions between the Sun and Earth's magnetic field can influence weather patterns and create phenomena like the auroras.
