Questions & Step-by-Step Solutions

Which of the following is true about the period of a satellite in a low Earth orbit compared to a satellite in a high Earth orbit?
  • Step 1: Understand what a satellite's period is. The period is the time it takes for a satellite to complete one full orbit around the Earth.
  • Step 2: Know that satellites can be in different types of orbits: low Earth orbit (LEO) and high Earth orbit (HEO).
  • Step 3: Recognize that in low Earth orbit, satellites are closer to the Earth.
  • Step 4: Remember that the gravitational pull from the Earth is stronger when you are closer to it.
  • Step 5: Realize that because of this stronger gravitational pull, satellites in low Earth orbit move faster.
  • Step 6: Conclude that since they move faster, the time (or period) it takes for them to complete one orbit is shorter compared to satellites in high Earth orbit.
