“What Are Stars Made Of?” is a significant topic on which students may be asked to write a paragraph in their school exams. Stars are massive, glowing balls of gas, mainly hydrogen and helium. They shine brightly by producing energy through fusion. Please check the various versions (in 100 words, 150 words, 200 words, and 300 words) provided below for the paragraph.
Paragraph on ‘What Are Stars Made Of?’ in 100 Words
Stars are huge balls of gas. They are made mostly of hydrogen and helium. These gases are very hot. Inside a star, hydrogen atoms come together and form helium. This process releases a lot of energy, which makes the star shine. The energy from stars is what makes them so bright and hot. The Sun is a star. It gives us heat and light, which we need to live. Stars are of different sizes, and some are much bigger than our Sun. Stars are far away, but their light reaches us from space.
Paragraph on ‘What Are Stars Made Of?’ in 150 Words
Stars are big, burning balls of gas. Most of the gas in a star is hydrogen and helium. These gases are very hot and can change into different forms of energy. Inside a star, hydrogen atoms come together to make helium. This process is called nuclear fusion. It creates a lot of heat and light, which is why stars shine. The Sun is a star, and it gives us heat and light, which help us live on Earth. Some stars are much bigger than the Sun, while others are smaller. Even though stars are very far away, we can still see their light shining in the night sky.
Paragraph on ‘What Are Stars Made Of?’ in 200 Words
Stars are huge, glowing balls of gas that are made mostly of hydrogen and helium. The gases in a star are very hot, and inside the star, they change into different forms of energy. The process that makes stars shine is called nuclear fusion. During nuclear fusion, hydrogen atoms combine to form helium. This process creates a lot of heat and light, which makes the star shine brightly. The Sun is the closest star to Earth, and it gives us heat and light. Without the Sun, life on Earth wouldn’t be possible.
Stars come in different sizes. Some are much bigger than the Sun, while others are smaller. Even though stars are very far away, we can still see their light. When we look up at the night sky, we see many stars shining. The light we see is from stars that are millions of miles away. Some stars burn out and stop shining after millions of years, while others may continue shining for billions of years. Stars are an important part of the universe, and they help us understand the world beyond Earth.
Paragraph on ‘What Are Stars Made Of?’ in 300 Words
Stars are giant balls of gas, mostly made up of hydrogen and helium. These gases are so hot that they form energy. Inside the star, hydrogen atoms come together in a process called nuclear fusion. This process creates helium and releases a lot of energy. The energy makes the star shine very brightly. This is why stars like the Sun give off heat and light. The Sun is the closest star to Earth, and without it, life on our planet wouldn’t be possible. It gives us warmth and energy, helping plants grow and keeping us alive.
Stars come in different sizes. Some stars are much bigger than the Sun, while others are smaller. The size of a star affects how bright it is and how long it will live. Some stars shine for billions of years, while others burn out in just a few million years. Stars are so far away that we can’t see them clearly with our eyes. But their light travels through space and reaches Earth, so we can see them twinkling at night. Some stars are so far away that their light takes millions of years to reach us!
Stars can also be different colors. Some stars are red, while others are blue or yellow. The color of a star tells us how hot it is. Hot stars are blue, and cooler stars are red. Over time, stars can change. Some stars turn into red giants before they burn out, while others become white dwarfs or even black holes. Stars are fascinating because they help make up the universe and give us light to see in the dark.

Stars form from gas clouds, shine through nuclear fusion, and die as supernovae, black holes, or white dwarfs, depending on their mass.
How Do Sun Produce Light?
The Sun generates light through nuclear fusion, converting hydrogen into helium in its core, releasing vast energy as light and heat.
Why is the Sun hot?
The Sun is hot due to nuclear fusion in its core, where hydrogen atoms collide and fuse, releasing intense heat and energy.
Why Do Stars Twinkle At Night?
Stars twinkle because Earth’s atmosphere distorts their light as it passes through layers of varying air density, causing the flickering effect.
