How long does it take a satellite to orbit Earth?

The period of a satellite, or how long it takes to orbit the Earth one time, is dependent on its orbital altitude. Satellites in LEO, like the International Space Station, take about 90 minutes to orbit the Earth. Satellites in MEO take about 12 hours to do the same.


How far is a satellite from Earth in miles?

A geosynchronous orbit is a high Earth orbit that allows satellites to match Earth's rotation. Located at 22,236 miles (35,786 kilometers) above Earth's equator, this position is a valuable spot for monitoring weather, communications and surveillance.


How do they make sure satellites don't collide?

Spacecraft without onboard propulsion

The aerodynamic drag on small satellites in Low Earth orbit can be used to change orbits slightly to avoid debris collisions by changing the surface area exposed to atmospheric drag, alternating between low-drag and high-drag configurations to control deceleration.


How can you tell the difference between a shooting star and a satellite?

A satellite will move in a straight line and take several minutes to cross the sky. A meteor, or shooting star, will move in less than a fraction of a second across the sky. Observe the kind of light from the "star". A satellite will brighten and dim in a regular pattern as it crosses the sky.
