SOLAR SYSTEM

Detailed explanation-1: -An international crew of seven people live and work while traveling at a speed of five miles per second, orbiting Earth about every 90 minutes. Sometimes more are aboard the station during a crew handover. In 24 hours, the space station makes 16 orbits of Earth, traveling through 16 sunrises and sunsets.

Detailed explanation-2: -So, typically, for a circular orbit at a height of 300 km above the Earth’s surface, a speed of 7.8 km/s (28, 000 km/h) is needed. At this speed, the satellite will complete one orbit around the Earth in 90 minutes. Satellites have to move so quickly in order to compensate for the pull of Earth’s gravity.

Detailed explanation-3: -Viewing opportunities of the ISS can vary between one sighting a month to several a week, depending on your location and the orbit of the ISS.

Detailed explanation-4: -How far do you think light travels in a minute? To figure this out, multiply the distance that light travels in a second by 60 because there are 60 seconds in a minute. So light can travel 18, 000, 000 kilometers in one minute!

Detailed explanation-5: -But did you know that ISS experiences sunrise and sunset every 45 minutes? Yep, that’s a thing there and there’s a reason for it. The ISS completes one revolution of Earth in 90 minutes. And this makes it witness 16 sunsets and sunrises every day!
