A group of explorers make use of a newly discovered wormhole to surpass the limitations on human space travel and conquer the vast distances involved in an interstellar voyage. So even though the planets move at an incredible speed, it’s nothing compared to the vast and empty space. Take the sun for example, the Earth’s rotation speed (according to Wikipedia) is 1,674.4 km/h (on the equator) However, the sun appears more or less stationary observed over a small period of time. Exactly – The further the object is from the observer, the slower it appears to move. It’s simple geometry. All movement, displacement and velocity is relative to a point of reference, therefore we might as well assume u aren’t moving regardless of the situation. Let’s say u start an observation when the object u observe is at A position and finish ur observation when an object is at B position while u are at position C. The points make ‘ABC’ triangle with &lt,|BCA angle centered on you. You as an observer can only perceive the &lt,|BCA angle size (in real time angular speed) so the further the object is from you the longer the distance an object has to travel to make the same &lt,|BCA angle. If the distance is longer then the velocity has to be higher to make it in the same time. In space the distance is so huge that it takes massive amount of time to make a difference. It’s all about the angular speed. When you are on the high way for example and you see another car next to you, that car appears to be standing still, but in reality it’s standing still because you are both going at the same velocity. That’s not really the case since it would require all those space entities to move in the same direction, which would be the direction the spaceship is taking. Every time they enter a specific planets system, it’s a fair assumption that they are all going in the same direction. After that it’s a matter of relative velocity. That’s true when you take an unrelated object as a reference, but the ship still moves in relation to the planet and the velocity must be quite high. It’s impossible to have a low relative speed to an object with huge mass since u would start falling immidiately unless u waste a lot of fuel correcting the gravity. Velocity doesn’t have to be high. The acceleration just has to be positive in the direction you wish to go, which may or may not lead to high/low velocities. It is absolutely possible to have a low speed and still escape gravity.
