Is Saturn larger or smaller than the earth?
Considering you are asking if the sun will look larger or smaller on Saturn than it does on the Earth, the answer is that the sun will look smaller because the distance between the Earth and sun is less than the distance between Saturn and the sun. The farther you are from something, the smaller it looks.
Much smaller. Consider, the diameter of the rings of Saturn are larger than Saturn itself, and Saturn is the second largest planet in the solar system. The rings of Saturn have a diameter of about 280,000 Kilometers. Charon has a diameter of about 1,200 kilometers. In other words the rings of Saturn are are more than 200 times larger than Charon.
No planet is smaller than Neptune, but larger than Earth in diameter, but Uranus is there in mass. Uranus, even though larger, is less massive than Neptune. Neptune is a giant planet, but not as large as we believe. It is just 3 or 4 times larger than Earth in diameter, but is 16 times massive. Even Uranus is just 13 times. Jupiter and Saturn are much much bigger than all these planets.
