Star vs. Planet – How to Tell the Difference in the Night Sky

Have you ever looked up at the night sky and wondered, “Is that a star… or a planet?” You're not alone! This is one of the most common questions among beginner stargazers.

🌟 What Makes a Star?

Stars are massive, glowing balls of gas — often located light-years away from Earth. Because of their extreme distance and the effect of Earth’s atmosphere, stars appear to twinkle when we observe them from the ground.

🪐 What Makes a Planet?

Planets are much closer to Earth compared to stars. They don’t produce light but reflect sunlight. Because they’re closer and larger in apparent size, planets tend to shine with a steady, non-twinkling glow.

🔭 The Easy Trick to Know

• If it twinkles → it’s probably a star.
• If it shines steadily → it’s likely a planet.

This simple trick works almost every time — especially when identifying bright planets like Venus, Jupiter, or Saturn.
