Stars all seem to be made up of the same elements that are found on Earth, even though they can be different sizes, temperatures, and ages. Our Sun is an average-size star, maybe a little smaller than most stars. Stars the size of our Sun are known as Dwarf Stars.The largest stars can be 10 times larger across then the Sun. These are called Giant or SuperGiant stars.The very smallest stars are not much bigger than the planet Jupiter.tars all seem to be made up of the same elements that are found on Earth, even though they can be different sizes, temperatures, and ages.

The orbit of the Earth around the Sun is an ellipse. The distance is not fixed, but varies throughout its orbit. The average distance is about 150 million kilometers (149,597, â¦ 890 km) or about 93 million miles (92,955,820 mi.). The distance at perihelion is 147,098,290 km, the distance at aphelion is 152,098,232 km.e receive the same amount of solar radiation year-round. during the winter that radiation is spread over a larger surface and so it is less effective, during the summer the same radiation is on a smaller surface and so it is warmer.
