If the Earth rotates on its own axis at a speed of 30 kilometers per second, then why does the Earth look fixed from space ?

Description : If the Earth rotates on its own axis at a speed of 30 kilometers per second, then why does the Earth look fixed from space ?

Last Answer : Earth in its own orbit 29.8km / sec. Keeps moving fast. But when viewed from space, the earth looks fixed. The reason is 29.8km / sec. The speed seems too much to us but it is negligible to the ... earth is 12,667km. . So even if the earth rotates at that speed, it seems to be apparent from space.
