(i) “Earth-Twin” is called as_________.

1. Jupiter

(ii) The third nearest planet to sun is_________.

1. Venus 

2. Mercury 

3. Earth 

4. None of the above

Short Answer Question 3 Marks 

11. Explain Moon. 

Ans: A satellite is the Moon. There is just one moon on Earth, however some planets have multiple moons. The moon is only one-quarter the size of the Earth. Because the moon is so close to the earth in comparison to the other celestial bodies, it appears to be incredibly large. The moon is 3, 84,400 kilometres away from Earth.

12. Explain about the closest and third closest planet to the sun. 

Ans: The third closest planet to the sun is Earth. There are eight planets in the solar system, each of which orbits the sun in its own elongated orbit. Mercury is the planet that is nearest to the sun. Then comes Venus, and finally the Earth. Earth is the planet that is third from the sun.

13. What are planets? Explain. 

Ans: Planets lack their own light and heat sources. Planets are celestial bodies that do not have their own heat and light. The light from the stars is used to illuminate these planets. Planet comes from the Greek term Planetai, which meaning wanderer.

14. What is Constellation? 

Ans: A constellation is a group of stars that form distinct patterns. Different groups of stars make a variety of patterns in the night sky. Constellations are the names given to these groups. The constellations Saptarishi, or the small bear, and Ursa Major, or the big bear, are well-known.

16. What are the differences between Planets and stars? 

Ans: Stars are massive celestial objects. They are gaseous bodies that are extremely hot. Stars have their own light sources and emit it. They have their own source of warmth. Planets, on the other hand, are much smaller than stars. They lack their own source of heat. They don't even have their own light source. The stars provide them with illumination. Planets orbit the sun in a heliocentric orbit.

17. What do you mean by a solar system? 

Ans: The solar family is another name for the solar system. At the heart of the family is the sun, which serves as the head. The solar system is made up of the sun, eight planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune), as well as satellites, asteroids, and meteoroids. We dwell on the planet Earth. The qualities of life can only be found on the planet Earth. Because the earth is in the right orbit around the sun, it is neither too hot nor too cold.

18. Why is the earth a unique planet? 

Ans: The only known planet in the solar system with suitable conditions for life is Earth. The Earth's distance from the sun is about right, so it's neither too hot nor too cold. Its temperature is ideal for life to thrive. The amount of water required for survival on Earth is sufficient. Water makes up two-thirds of the earth's surface. It also contains the gases that are required for life to exist, such as oxygen and carbon dioxide. It is referred to as a one-of-a-kind planet for all of these reasons.

19. Why do we see only one side of the moon all the time? 

Ans: The moon is the earth's natural satellite. It appears larger since it is closer to the ground. The Moon is the closest celestial body to the Earth. The Moon takes around 27 days to complete one orbit around the Earth. One rotation on its axis also takes the same amount of time. We only see one side of the moon from the earth because it takes the same amount of time to rotate around the planet and on its axis.

20. What do you mean by universe? 

Ans: The universe is the greatest unit in which humans dwell. There are millions of galaxies in the universe. The Milky Way galaxy is an example of such a galaxy in the universe. The Milky Way galaxy includes our planet. This cosmos contains everything that exists. There is only one universe. The size of the cosmos is a subject of debate among scientists. They're on a mission to learn more about the universe. Many asteroids, planets, dark matter, stars, and other objects can be found in the universe.
