Answer:
Explanation:
we say that the sun is the biggest star because it is very closure to us and brightest say because it has hydrogen gas which can be converted into helium and its look bright. The largest known star (in terms of mass and brightness) is called the Pistol Star.
The planet mercury does not have any atmosphere because of it is very close to the sun and this effect the temperature on its surface because it absorb the heat of sun and they can't go outside the planet.
