The Sun
The Sun is a star: a huge ball of very hot gases. It is the star nearest to the Earth. It gives us heat and light, helps plants make food and dries our clothes. Its energy, called solar energy, runs solar panels and solar cookers. The Sun rises in the east and sets in the west. We must never look straight at it.
The Earth: day, night and a year
| Movement | What happens | Time taken |
|---|---|---|
| Spinning on its axis (rotation) | Day on the side facing the Sun, night on the other side | About 24 hours (1 day) |
| Going round the Sun (revolution) | One full year passes | About 365 days (1 year) |
The Moon
The Moon goes round the Earth, so it is the Earth's natural satellite. It has no light of its own; it shines by reflecting sunlight. It has no air or water and its surface has many craters. Neil Armstrong was the first person to walk on the Moon, in 1969. India's Chandrayaan-3 landed near the Moon's south pole in 2023.
| Phase | What we see |
|---|---|
| New moon | The Moon is dark; we cannot see it |
| Crescent | A thin curved slice is lit |
| Half moon | Half the face is lit |
| Gibbous | More than half is lit |
| Full moon | The whole round face is lit |
Stars and planets
Stars are far-away suns that make their own light. They look tiny because they are very far away, and they seem to twinkle. Sirius is the brightest star in the night sky. Star patterns are called constellations, such as the Great Bear (Saptarishi). Eight planets go round the Sun: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Planets do not make their own light.
Types of questions
- Fill in the blanks about the Sun, Moon and stars

- Order the planets
- True or false
- Day or night
- Reason questions about day, night and phases
Solved examples
Common mistakes
| Mistake | Correct idea |
|---|---|
| The Sun moves round the Earth | The Earth spins and goes round the Sun; the Sun only seems to move |
| The Moon makes its own light | The Moon reflects sunlight |
| The Sun is not a star | The Sun is a star, the one nearest to us |
| Stars disappear in the day | Stars are still there; sunlight hides them |
| The Moon really changes shape | We see different parts of its lit half |
| Planets twinkle like stars | Stars twinkle; planets shine steadily and do not make light |
Daily life
We wake with the sunrise, use solar lights and solar cookers, plan festivals by the Moon, watch the full moon at night and use calendars based on the Earth's year.
