Q. Consider the following celestial bodies:
  1. Moon
  2. Earth
  3. Venus
Which one of the following correctly represents the increasing order of their albedo (from lowest to highest)?

Answer: 1 2 3
Notes: The albedo of the Moon is approximately 0.12, Earth’s albedo is about 0.37, and Venus has a very high albedo of around 0.65 due to its thick cloud cover. Therefore, the correct ascending order is Moon (1), Earth (2), and Venus (3), i.e., 1 2 3.
