It provides all conditions for space experiments, cargo delivery is not too expensive, and maintaining the orbit does not consume. The station orbits the earth at an average altitude of 400 kilometres (250 miles) [12] and circles the earth in roughly 93 minutes, completing 15.5 orbits per day. How much energy must be expended to rocket the satellite out of the earth’s gravitational influence?

Calculate the distance from the center of the earth to the satellite. The international space station orbits the earth at an incredible altitude of around 400 kilometers (250 miles), placing it firmly within the thermosphere. Whereas the minimum possible iss approximate distance is 330 km.
A satellite orbits the earth at a height of 400 km above the surface.
“the international space station orbits the earth at an average distance of approximately 248 miles (400 kilometers)”. The iss travels at this speed to maintain an. We need to convert this to meters and. The international space station (iss) serves as a monumental achievement in global cooperation, orbiting earth at an average.
The international space station (iss) orbits approximately 400 kilometers above earth with an orbital speed of 7.66 km/s and an orbital period of approximately 50 billion years. Therefore, an orbit around 400 km is optimal: On average it orbits at an altitude of around 400 km above earth (that’s about the distance from london to edinburgh straight up!). At that height, it whips around the planet.

The iss orbits earth at an average of 400 km (248 miles) above the surface traveling approximately 8 km per second (17,900 mph).
International space station (iss) statistics: The height of the satellite above the earth's surface is given as 400 km.
