depends were you go because some planets are so far away it would take years to reach them (just the ones in our solar system) not to mention how long and if you come back depends were you go because some planets are so far away it would take years to reach them (just the ones in our solar system) not to mention how long and if you come back
In order not to miss the window of return flight.
A building, by definition, generally stays in the same place. The Space Station is constantly orbiting the earth. It is therefore not a building.
if the earth rotates in the same place
You might contrast objects in open orbit with those in closed orbit such as the Earth. Up to an approximation, and relative to the Sun, when the Earth completes an orbit around the Sun it returns to the same place in space. Thus it can be said to 'close' its orbit. Objects that do not return to the same point in space are said to be in open orbit. They might be following parabolic or hyperbolic paths, or some other more complicated locuses of points.
A Year. Although the length of a year varies each year.
Yes and no. On earth, there are time zones based on where you are located on earth. There are no time zones in space.
Fancifully you might. I assume you're thinking that 'space' might be like like a perfect sphere and traveling due, which-ever-way, after several billion eons (in a static universe) you, or your ghost, or your indestructible, incorruptible space ship, would eventually return to the same spot it left.
Yes gravity is the same size on earth but not in outer space where there is no gravity.
Yes. Every time the earth orbits the Sun it returns to the same spot
The same as other matter and energy in space.
The same as on Earth - Stars
it orbits an object in space.
