(ORDO NEWS) — In general, what does it mean to fall around the Earth? Earth’s gravity pulls objects down to its surface.
Gravity also pulls on the space station, in our case the International Space Station. As a result, it constantly falls towards the Earth’s surface, but it also moves at a very high orbital speed – approximately 28,000 kilometers per hour.
It moves at a speed that matches how the Earth’s surface curves. If a person throws a tennis ball on Earth, gravity will cause its trajectory to curve downward toward the ground, and it will hit the ground fairly quickly.
The orbiting spacecraft is moving at the “correct speed” so that its fall curve matches the curvature of the Earth.
Because of this, the spacecraft continues to fall towards the Earth, but never hits it. As a result, all devices fall around the planet. For the same reason, the Moon remains in orbit around the Earth. The moon also falls around the earth.
