To monitor global climate and environmental changes from space, scientists deploy various artificial satellites into different orbits around the Earth. Two such key assets are the International Space Station (ISS) and the Meteosat-11 meteorological satellite.
Which row in the table below correctly describes the orbit type and approximate orbital period for these two space systems?
