Fuel consumption increases exponentially the closer to Earth the orbit is. The International Space Station (ISS) originally orbited at an average of 350 km (217 mi) from Earth, but was boosted to an average of 400 km (248 mi) in 2011. [14] This allowed the ISS to go from an average fuel use of 8,600 kg per year to 3,600 kg per year.

The International Space Station is in LEO about 400 to 420 kilometres (250 to 260 mi) above the Earth's surface. [14] The station’s orbit decays by about 2 km/month (1.2 mi/month) and consequently needs re-boosting a few times a year. The Iridium telecom satellites orbit at about 780 km (480 mi).
For Earth this means a period of just under 12 hours at an altitude of approximately 20,200 km (12,544.2 miles) if the orbit is circular. [16] Molniya orbit: A semi-synchronous variation of a Tundra orbit. For Earth this means an orbital period of just under 12 hours.
380 Earth radii (very inaccurate, true=16000 Earth radii) Aristarchus of Samos made a measurement of the distance of the Sun from the Earth in relation to the distance of the Moon from the Earth. The distance to the Moon was described in Earth radii (20, also inaccurate). The diameter of the Earth had been calculated previously.
The Boeing Starliner spacecraft is now scheduled to undock from the International Space Station and return to Earth on June 22, NASA said on Friday, giving more time to finalize planning for the ...
Earth's atmosphere photographed from the International Space Station.The orange and green line of airglow is at roughly the altitude of the Kármán line. [1]The Kármán line (or von Kármán line / v ɒ n ˈ k ɑːr m ɑː n /) [2] is a conventional definition of the edge of space; it is widely but not universally accepted.
