Most of cargo operations take place between a ship and a land-based terminal. Nevertheless it sometimes can be useful to transfer cargo from one ship to another in the open sea and this is called a ship-to-ship operation. One vessel will act as the terminal whilst the other one will moor.
The moon is roughly 238,000 miles away from Earth. Earth orbits the sun. Earth is roughly 93 million miles from the Sun. The Sun is the center of our solar system. The Earth's Moon is located in orbit around the Earth. There are other moons in orbit around other planets. There are many moons in our solar system.
