Everyone would have heard about International Space Station or ISS in Tv and News. But does anyone knows how large it is and how fast it rotates the Planet Earth? Let’s know,
ISS is the world most expensive and largest spacecraft ever built. The dimensions will be approximate,
Length – 356 feet (109 meters)
Width – 240 feet (73 meters
Weight – 450 tons (408,000 kg)
It’s little larger compared to the football ground.
It’s so large that it is visible on naked eyes from the ground and also very clearly seen after the sun set. It circles the Earth on every 90 minutes at the speed of 4.8 miles (7.7 km) per second, flying in one of the lowest orbits possible at approximately 242 miles (390 km) above Earth.
