Our Universe for Class 2 (EVS): Sun, Moon, Stars, 8 Planets & Day and Night
Every evening the Sun disappears, and the Moon and stars come out. So where does the Sun go at night? In this lesson from Param Tuition Bureau, Class 2 children find the answer with just a torch and a ball, and meet our neighbours in space.
1. The Sun, the Moon and the Stars
- The Sun is a star. It is a huge ball of very hot gases and gives us heat and light.
- The Moon goes around the Earth. It has no light of its own. It shines because sunlight falls on it, like a torch shining on a steel plate.
- Stars are also suns, but they are very, very far away.
2. Why Do Stars Look So Tiny?
A bus near you looks big. The same bus far down the road looks tiny. Stars look tiny for the same reason: they are very far away. Some stars are even bigger than our Sun.
3. The 8 Planets
Eight planets go around the Sun, each in its own path called an orbit.
| Planet | Fun fact |
|---|---|
| Mercury | Smallest, and closest to the Sun |
| Venus | Hottest planet |
| Earth | Our home, the blue planet |
| Mars | The red planet |
| Jupiter | Biggest planet |
| Saturn | Has beautiful rings |
| Uranus | Spins on its side |
| Neptune | Farthest from the Sun |

4. Activity: Make Day and Night
You need a torch, a ball or an orange, a small sticker (for India) and a dark room. Shine the torch on the ball: the side facing the torch has day, and the other side has night. Now slowly spin the ball. The sticker moves from day to night and back again. The Sun never goes home. Our Earth spins!
5. Rotation and Revolution
- Rotation: the Earth spins like a top. One spin takes 24 hours and gives us one day and one night.
- Revolution: the Earth goes around the Sun. One full round takes 365 days, which is one year.
Because the Earth is a little tilted, different places get more sunlight at different times of the year. That's why we have summer and winter.

Our Universe for Class 2 (EVS): Sun, Moon, Stars, 8 Planets & Day and Night — FAQs
Is the Moon a star or a planet?
Neither. The Moon has no light of its own and simply goes around the Earth, shining only because sunlight falls on it, like light reflecting off a steel plate.
Why do stars look so small in the sky?
Stars are suns too, but they are extremely far away. Just like a bus looks tiny far down the road, distance makes even huge stars look like tiny points of light.
What is an easy way to remember the order of the 8 planets?
Use the memory trick "My Very Easy Method Just Speeds Up Naming" — the first letter of each word matches Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune in order from the Sun.
What causes day and night?
The Earth spins on its own axis, a movement called rotation, completing one full spin every 24 hours. The side facing the Sun has day, and the side facing away has night.
