Okay kiddo, have you ever seen those shapes that represent different planets like the sun, moon or stars? These shapes are called "planet symbols". They help us identify and remember which planet is which. Just like how you have a name and your friends have names so we can easily call each other, planets also have names and symbols to make it easier for scientists to study and talk about them.
Now, did you know that each planet's symbol has a special meaning? For example, the symbol for the sun looks like a big circle with a dot in the middle. The circle represents the sun's mass and energy, while the dot symbolizes the sun's fiery core.
Other symbols have different meanings too. The symbol for Venus, the planet of love and beauty, looks like a circle with a cross underneath it. The cross represents a hand-held mirror, which was a symbol of beauty in ancient times.
So, knowing these symbols helps astronomers and scientists identify the planets and talk about them in a way that the rest of us can understand. Isn't that cool?
