All of your observations in the Small Worlds Sim have assumed you were viewing the solar system from the Sun. Now we provide Earth as a reference point for your observations. Earth is a distance of 1 AU away from the Sun and is an easy number to work with. Take a look at the Small Worlds Sim again. Observe the objects you have identified closely. How fast are they moving compared to Earth

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?

The earth is constantly spinning on its axis, like you might spin a basketball on your finger. it is this spinning of the earth that causes
