E. Very Short Answers

  1. A star is a celestial object that produces its own light and heat.
  2. Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.
  3. A constellation is a recognizable apparent pattern formed by stars in the sky.

  8. An exoplanet is a planet that revolves around a star other than the Sun.

F. Short Answers

  1. The Sun is much closer to Earth than other stars, so it appears much larger and brighter.
  2. Stars produce their own light, while planets do not. Planets are seen because they reflect light from their star.
  3. Rotation is spinning around an object’s own axis. Revolution is movement around another celestial body.
  4. The Moon reflects sunlight towards Earth.
  5. The Moon has no substantial atmosphere, so there is very little erosion to remove or soften impact marks.
  6. Asteroids are small rocky bodies. Most of them are found in the asteroid belt between Mars and Jupiter.
  7. Light pollution is excessive artificial light at night. It makes faint stars and other celestial objects difficult to see.
  8. Telescopes collect more light and magnify distant objects, allowing astronomers to study objects that are too faint or distant for the naked eye.

G. Think and Answer

Answers may vary. Students should give logical explanations based on the ideas of the chapter.

H. Correct Order

  1. Mercury, Venus, Earth, Mars.
  2. Moon, Earth, Solar System, Galaxy.

J. Application-Based Answers

  1. Possible reasons include city light pollution, bright buildings, cloudy conditions or an unsuitable observation location.
  2. Ancient travellers could use recognizable stars and constellations to identify directions.
  3. The Moon is not a star. It does not produce its own light; it reflects sunlight.
  4. A telescope collects and focuses much more light than the naked eye and can reveal distant, faint objects.

K. India and Space

  1. Chandrayaan-1 was India’s first lunar mission.
  2. 2023.
  3. August 23 commemorates India’s successful Chandrayaan-3 soft landing near the Moon’s south polar region.
  4. Hanle is high, dry, has low atmospheric moisture and very little artificial light, making it suitable for astronomical observations.

L. Extra Challenge

Answers should demonstrate understanding and reasoning. Accept scientifically correct explanations expressed in the student’s own words.
