Question 3. Which of the following is not a member of our Solar System?

(i) Sirius

(ii) Comets

(iii) Asteroids

(iv) Pluto

Answer:

(i) Sirius

Sirius is a star, so it is not part of our Solar System.

(i) Sirius - It's the brightest star in the night sky, located in the constellation Canis Major. It's far away from the Sun.

(ii) Comets- Made of ice, dust, and rock, and they orbit the Sun in long, elliptical paths.

(iii) Asteroids- Rocky objects mostly found in the asteroid belt between Mars and Jupiter. They also orbit the Sun.

(iv) Pluto- It was once considered the ninth planet, but now it's called a dwarf planet. It still belongs to the Solar System and orbits the Sun.

Question 4. Which of the following is not a planet of the Sun?

(i) Jupiter

(ii) Pluto

(iii) Neptune

(iv) Saturn

Answer:

(ii) Pluto

Pluto is no longer considered a planet; it's now classified as a dwarf planet by scientists.

Question 5. Which is the brighter star, the Pole Star or Sirius?

Answer:

Sirius is the brighter star. It's the brightest star in the night sky, while the Pole Star (Polaris) is bright but not as bright as Sirius.

Question 6. An artist’s representation of the Solar System is given in Fig. 12.12. Is the order of the planets correct? If not, write the correct order in the boxes in the figure.

Answer:

The image shows the planet of our solar system, which is in order-

Mercury

Venus

Earth

Mars

Jupiter

Saturn

Uranus

Neptune

Question 7. A portion of the night sky with stars is shown in Fig. 12.13. Look carefully and identify the groups of stars that form the patterns—the Big Dipper and the Little Dipper. Draw lines to connect the stars for these patterns and label them. Also, identify and label the Pole Star. You may refer to Fig. 12.4 for help.

Answer:

Big Dipper (a part of the Ursa Major constellation)- it looks like a big spoon or ladle.

Little Dipper (part of Ursa Minor).

The last star on the handle of the Little Dipper is the Pole Star (also called Polaris).

Question 8. A portion of the night sky is shown in Fig. 12.14. Draw lines to connect the stars for Orion and label the star Sirius. You may refer to Fig. 12.3.

fig. 12.14

Answer:

In Fig. 12.14, you can identify Orion by finding the three bright stars in a straight line; these form Orion’s Belt.
Around this belt, there are four more bright stars that form a quadrilateral or hourglass shape, completing the Orion constellation.
Once Orion is located, look slightly to the left and down from the belt; the brightest star in that region is Sirius. It is not part of Orion but is the brightest star in the night sky and lies close to Orion.

Question 9. You can see stars fading away at dawn and appearing at dusk. During the day we do not see the stars. Explain why.

Answer:

We can not see stars during the day because the bright sunlight scatters in the sky and hides the light of the stars. The stars are still there, but their light gets overpowered by the sun. At dusk, when the sun sets, the sky becomes dark again, and stars start appearing. At dawn, the rising sunlight again fades the stars away.

Question 10. During a clear night, try to observe the Big Dipper 3–4 times at an interval of 2 to 3 hours. Also try to locate the Pole Star each time. Does the Big Dipper appear to move? Draw a rough sketch to illustrate this, mentioning the time in each case.

Answer:

Yes, the Big Dipper appears to move in the night sky. If you observe it every 2–3 hours, you will notice that its position changes slowly around the Pole Star. This is because the Earth rotates and so the stars seem to move in circles around the Pole Star.

Question 11. Think about the night sky and write a poem or a story on it.

Answer:

Once upon a time, in a small village there was a curious little girl named Salma. She used to lay down on her rooftop every night and look up at the twinkling stars. She adored the way they gleamed like tiny diamonds on a black bedspread. One evening, she saw a bright star that never moved. Her grandfather told her that it was the Pole Star and it always stayed in the same place to guide the travelers. She was amazed by this fact and started dreaming about the stars and sky every night.

One night, the stars whispered to Salma, “We are not still. We dance slowly around the Pole Star every night.” She watched patiently and noticed the Big Dipper changing its place in the sky after every few hours. From then on, she started writing messages to the stars in her diary and felt like they were her friends. The night sky was no longer just beautiful but is full of infinite stories.

NCERT Solutions of Class 6 Science Chapter 12 Summary

The chapter Beyond Earth will introduce you to celestial objects like stars, planets, the moon, and constellations. It will explain to you how the stars emit their own light while planets reflect sunlight and revolve around the Sun. The chapter will also cover the phases of the moon and will introduce constellations like Orion and the Big Dipper. It will tell you about comets, meteors, man-made satellites and other celestial bodies, including the Pole Star. This chapter will help the students to understand the wonders of the night sky and our place in the solar system.

Approach to Solve NCERT Solutions for Class 6 Science Chapter 12

The chapter Science Beyond Earth tells about the celestial bodies, solar system and space. It creates curiosity about the universe, how vast it is, how much do we know about it, and how much we do not. Earth is part of a larger cosmic system and this chapter combines basic astronomy with real-life observations.

1. Understand celestial bodies:

• About the Sun, Moon, planets, stars, asteroids, and satellites
• Focus on their characteristics and differences (e.g., stars emit light, planets do not).

2. Memorize the solar system:

• Know the names and order of the planets (from Mercury to Neptune)
• Understand the movement of planets around the Sun and the Earth's rotation and revolution

3. Phases of the moon:

• Understand how and why the Moon changes shape (new moon, full moon, crescent, etc.).
• Know the concept of one lunar month (~29.5 days).

4. Relate Concepts to Real Observations:

• Use daily experiences like sunrise/sunset, moon sighting, and seasons to relate textbook concepts.
• This improves understanding and makes answers realistic.
