Which planet has a mass that is approximately one-tenth that of Earth?

  1. Venus

  2. Mars

  3. Mercury

  4. Jupiter

The correct answer is: Mars

Mars has a mass that is approximately one-tenth that of Earth, making it the correct choice in this context. To provide further context, Mars has about 10.7% of Earth's mass, which aligns with the description in the question. Venus, while similar in size and composition to Earth, has a mass that is about 82% of Earth's. Mercury, being the smallest planet in the solar system, has a mass that is roughly 38% of Earth's. Jupiter, the largest planet, has a mass that is significantly greater than Earth's, at about 318 times that of Earth. Thus, the unique relationship of Mars with Earth's mass makes it the correct answer regarding the description provided in the question.
