What is a planet?
A planet is a celestial body that rotates around a star and has enough mass for its own gravity to allow it to achieve hydrostatic equilibrium, that is, a rounded shape.
- It is not a light source
- Orbit around a star
- Has enough mass to be round
What is a star?
A star is a gaseous celestial body that produces its own light through the nuclear fusion of hydrogen into helium in its core.
- It is a source of light
- It has its own planetary system
- It is more massive than a planet
Key differences
In short, the main difference between a planet and a star is that planets do not produce light themselves, while stars do. Furthermore, planets revolve around stars, while stars have their own planetary system. Another important difference is that stars are much more massive than planets and have a different formation process.
In conclusion
In conclusion, although they sometimes appear similar, planets and stars are very different celestial bodies. Planets are rocky or gaseous bodies that orbit a star, while stars are gaseous celestial bodies that produce their own light.
Remember to differentiate between a planet and a star when observing the night sky!
