A satellite is otherwise known as a travelling companion so moon is a satellite even though we think of satellites as man made objects.
Both pictures are satellites but which one is more beautiful? Don't get me wrong...scientists were very clever in inventing a man made satellite but I think nature is very capable of creating beautiful things that also serve a great purpose.
Looking at all the planets in the solar system, Earth is by far the most beautiful and fascinating planet.
Above is a picture of Earth and below is a picture of Mercury. Which one do you think is more beautiful? Uranus is also a beautiful colour but still it is boring being one colour where as Earth is a swirl of different shades of blue, white, green and many other colours. It almost looks like Earth is a painting.
