When it comes to astronomy, stars and planets are two of the most fascinating celestial bodies. But what is the difference between them?Stars are large, luminous spheres of gas that produce their own light and heat. They are made up of mostly hydrogen and helium, and they are held together by their own gravity. Stars can range in size from small red dwarfs to massive blue giants.
Our Sun is a star.Planets, on the other hand, are much smaller than stars. They are solid bodies that orbit around stars. Planets are made up of rock and metal, and they do not produce their own light or heat. Instead, they reflect the light of the star they orbit.
Planets can range in size from small rocky worlds like Mercury to gas giants like Jupiter.The main difference between stars and planets is that stars produce their own light and heat, while planets do not. Stars also have much higher masses than planets, which means they have much stronger gravitational fields. This is why planets orbit around stars, but stars do not orbit around planets.Another difference between stars and planets is that stars are made up mostly of hydrogen and helium, while planets are made up mostly of rock and metal. This means that stars are much hotter than planets, which is why they produce their own light and heat.Finally, stars live much longer than planets.
Stars can live for billions of years, while planets typically only last for a few million years before they are destroyed by their parent star.In conclusion, stars and planets are two very different celestial bodies. Stars produce their own light and heat, while planets do not. Finally, stars live much longer than planets.
