NCERT Solutions Class 6 Science Chapter 12 - Beyond Earth
Starting a trip into the universe in Class 6 is a truly mind-expanding experience. The NCERT Solutions for Chapter 12: Beyond Earth will make this exploration of our universe easier and clearer and also present it in a manner that is appropriate and engaging for young minds ready to embark on an exploration of the enormous and mysterious space above them.
Science is primarily about understanding the world around us from the smallest particle to the biggest celestial object. It is primarily an empirical process driven by observation, experimentation, and evidence to try and understand the "what" and "why" behind natural occurrences. Studying space helps us teach curiosity, deep questioning, and logical thinking, which are crucial tools when thinking in a scientific way, whether in or out of school, and when wondering about our role in the universe.
The NCERT Solutions for Class 6 Science Chapter 12 helps students build a fundamental understanding of astronomy and space science, while encouraging students to stay curious about the wonders above them. By undertaking these solutions, students start to think of science not just as a school subject, but as a way of stepping back and exploring the universe with curiosity, clarity, and logical reasoning.

2.0Key Concepts in Chapter 12: Beyond Earth
In the NCERT textbook (especially the "Curiosity" edition) for Class 6 Science, the chapter "Beyond Earth" typically introduces students to fundamental concepts of space, celestial bodies, and our solar system.
- Introduction to the Night Sky: In this chapter the text begins with an introduction to night sky features and acts as a natural motivator of curiosity about stars and the patterns they create.
- Stars and Constellations: The text then convenes to stars and introduces understanding stars as luminous bodies and the concept of constellations, groups of stars that form forms patterns and coordinates, then outlines some examples, as noted below: - Big Dipper - Sapta Rishi - Pole Star - Dhruva Tara - Other recognizable constellations.
- Nightsky watching: Practical aspects of nights sky observations were discussed observing the nightsky and aspects of observations like selections of the location for best observations (away from artificial light), sky maps or sky apps to assist with identification, and to give you eyes time to adjust to darkness.
- Our solar system: The chapter continues with an in depth understanding with the Sun in the centre of our solar system to introduce the eight planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune). Each planet was introduced in the order of their locations away from the sun and identified some identifiable features of the planet. (Such as, Earth the Blue Planet; Mars the Red Planet; Venus the Morning Star/Evening Star).
- Moons, Asteroids, and Comets: The chapter introduces other celestial bodies within our solar system, such as natural satellites (like Earth's Moon), asteroids (rocky objects mainly in the asteroid belt), and comets (icy bodies with glowing tails).
- Beyond Our Solar System - Galaxies and the Universe: It provides a glimpse into the vastness of space, introducing the concept of galaxies, including our own Milky Way Galaxy, and the broader universe. The ongoing search for life beyond Earth is often touched upon.
- Human Exploration of Space (Optional/Brief): Some versions may briefly mention human endeavors in space, such as satellites or lunar missions (e.g., Chandrayaan).
- Light Pollution: The impact of artificial light on our ability to observe the night sky and its environmental implications are sometimes discussed, encouraging responsible lighting practices.
Here are some common subtopics covered in this chapter:
- Introduction to the night sky
- Stars and their properties
- Constellations: Ursa Major (Big Dipper/Sapta Rishi), Ursa Minor (Little Dipper), Orion, Pole Star (Polaris/Dhruva Tara)
- Importance of constellations for navigation
- Our Solar System: The Sun and the Eight Planets
- Characteristics of planets (e.g., Earth - Blue Planet, Mars - Red Planet, Venus - Morning/Evening Star)
- Moons/Natural Satellites (e.g., Earth's Moon)
- Asteroids and the asteroid belt
- Comets (e.g., Halley's Comet)
- Galaxies (e.g., Milky Way Galaxy)
- The vastness of the Universe
- Observing the night sky
- Light pollution and its effects

Solution
1,3,2,4,5,7,6,8
- A portion of night sky with stars is shown in Fig. Look carefully and identify the groups of stars that form the patternsthe 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. for help.
Solution
- A portion of the night sky is shown in Fig. Draw lines to connect the stars for Orion and label the star Sirius. You may refer to figure.
Solution
- You can see stars fading away at dawn and appearing at dusk. During the day we do not see the stars. Explain why?
Solution
We are unable to see stars during the day due to a primary reason sun's intense brightness, which overpower the light emitted by stars.
Furthermore, the bright sky during the day reduces the contrast between stars and the background rendering them invisible to the naked eye.
- 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.
Solution
The Big Dipper appears to move around the Pole Star due to the rotation of the Earth. Over a few hours, its position changes, making it seem as if it is rotating around the Pole Star.
- Think about the night sky and write a poem or a story on it.
Solution
Stars are twinkling, moon is bright. Shining softly through the night. The sky calms, the world is till, the night is a secret, time to change.
