Question

Statement I: In low earth orbits, the satellites complete one revolution of earth in 2 to 24 hours.
Statement II: Medium earth orbits are also called polar orbits.

• A.
  Statement I is correct and statement II is incorrect
• B.
  Statement I is incorrect and statement II is correct
• C.
  Both the statements are correct
• D.
  Both the statements are incorrect

Answer 1

The correct option is B

Statement I is incorrect and statement II is correct

If the height of the satellite orbit above the earth’s surface is in between 180 km and 2000 km, the orbits are called Low earth Orbits. The satellites in low earth orbits complete one revolution in around 90 minutes. A typical LEO satellite orbits the earth in less than two hours

If the height of the satellite orbit above the earth’s surface is in between 2000 km and 35780 km, the orbits are called medium earth orbits. To study polar regions, elliptical medium earth orbits passing over the polar region are used. These orbits are called polar orbits.

Therefore, statement I is incorrect and statement II is correct.
