<span>These stars tend to be much larger and much hotter than our sun. This is because they have more hydrogen with which to fuse into helium, and this increased level of fuel keeps the overall temperature more elevated than our own star. Over time, the temperature, brightness, and size will decrease as the amount of fuel decreases.</span>
