What this chapter is about
This chapter takes you on a journey beyond our planet Earth. You will learn about the sky we see at night, the Moon, the Sun, stars, and planets. You will discover what makes up our solar system and how Earth is just one small part of a much bigger universe.
Key ideas
- Stars are huge balls of hot, glowing gases that produce their own light and heat. The Sun is the star closest to Earth.
- Planets are large objects that move around a star. They do not produce their own light but reflect the light of their star.
- The Solar System is the Sun and all the objects that move around it, including eight planets, moons, asteroids, and comets.
- The Moon is Earth's natural satellite. A satellite is an object that moves around a planet. The Moon takes about 27 days to go around Earth once.
- The Moon appears to change shape over a month. These shapes are called phases of the Moon. We see different phases because sunlight falls on different parts of the Moon as it moves around Earth.
- Earth rotates (spins) on its axis once every 24 hours. This rotation causes day and night.
- Earth revolves (moves in a path) around the Sun once every 365 days, which we call one year.
- Constellations are groups of stars that appear to form patterns in the night sky. Saptarishi (the Big Dipper, part of the constellation Ursa Major) looks like a big ladle or question mark.
Formulas and facts to remember
- The eight planets in order from the Sun: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.
- Memory trick for planets: My Very Eager Mother Just Served Us Noodles (first letter of each word matches the first letter of each planet).
- The Sun is about 150 million kilometres away from Earth.
- Light from the Sun takes about 8 minutes to reach Earth.
- The Moon is about 3,84,000 kilometres from Earth.
- Jupiter is the largest planet; Mercury is the smallest planet in our solar system.
- A full moon and a new moon each appear once in about 29 days.
- Earth is the only planet in our solar system known to have liquid water and life.
Common mistakes
- Thinking the Moon produces its own light → The Moon only reflects sunlight; it has no light of its own.
- Believing stars are smaller than planets because they look tiny → Stars are actually much larger than planets, but they look small because they are extremely far away.
- Confusing rotation and revolution → Rotation is spinning in place (causes day and night); revolution is moving around another object (causes a year).
- Thinking Pluto is still a planet → Scientists reclassified Pluto as a dwarf planet in 2006 because it has not cleared its orbit of other objects.
- Believing the Sun moves around Earth → Earth and other planets revolve around the Sun, not the other way around.
Quick revision
- The Sun is a star; planets move around it and reflect its light.
- Eight planets orbit the Sun: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.
- Earth's rotation causes day and night; its revolution causes a year.
- The Moon orbits Earth and shows phases because we see different sunlit parts.
- Stars twinkle; planets usually do not.
- Constellations are patterns of stars, like Saptarishi.
