FAQs on Earth and its Natural Satellites - 2 Class 5 Worksheet Science

1. What is the definition of a natural satellite?
Ans. A natural satellite is an object that orbits a planet, dwarf planet, or small solar system body. It is also known as a moon. Earth has one natural satellite called the Moon.
2. How does the Moon affect Earth?
Ans. The Moon affects Earth in various ways. It causes the tides in our oceans due to its gravitational pull. It also stabilizes Earth's axial tilt, which is responsible for our seasons. Additionally, the Moon's presence in our sky has influenced human culture, navigation, and even the behavior of some animals.
3. What is the distance between Earth and the Moon?
Ans. The average distance between Earth and the Moon is about 384,400 kilometers (238,900 miles). This distance can vary as the Moon follows its elliptical orbit around Earth.
4. How long does it take for the Moon to orbit Earth?
Ans. The Moon takes approximately 27.3 days to complete one orbit around Earth. This period is known as the sidereal month. However, due to Earth's orbit around the Sun, it takes about 29.5 days for the Moon to go through its full phase cycle, known as the synodic month.
5. Can natural satellites exist around other planets?
Ans. Yes, natural satellites can exist around other planets. In fact, most planets in our solar system have moons of their own. For example, Jupiter, the largest planet, has at least 79 known moons. Saturn has over 80 moons, including its famous rings. These moons play important roles in the dynamics and characteristics of their respective planets.
