Why Are Comets So Bright When They Approach the Sun?

Comets are like frozen snowballs that travel through space. When they get close to the sun, the ice inside them starts to melt and turn into gas, creating a glowing cloud around the comet. This cloud reflects sunlight, making the comet look super bright, especially when it's near Earth.
