I am the Sun, a hot ball of glowing gases. I am a yellow dwarf star. I keep Earth warm enough for living things there to thrive. I give animals light so they can see. When I die, I think that I might turn into a white dwarf.

Hello! My name is Mercury! I am the closest planet to the Sun. But I am not the hottest. Venus is hotter than me because Venus has a thick atmosphere, and I have a thin one. My atmosphere does not trap much heat. I am also the smallest planet.

Hello! My name is Mars! I am a small planet. I look red because metal in the rocks on my surface have rust. I might look hot, but my temperature isn't much different than Earth's. That is why I can have ice on me, well, at the poles. I am next to Earth, and some Earth animals are coming to live on me!
