The planet with the highest number of moon is

Step 1: Analyze the question The question asks which of the listed bodies has the most moons. It is really an astronomy/general science question, even though it is labeled Chemistry.

Step 2: Recall the facts

• Earth: 1 moon
• Venus: 0 moons
• Pluto: classified as a dwarf planet since 2006 (it has 5 known moons)
• Uranus: 28 known moons
• Jupiter: about 95 known moons, one of the largest counts in the Solar System

Step 3: Compare Of the options, Jupiter has far more moons than Earth, Venus, Pluto, or Uranus. Even when the question was set in 2008, Jupiter led among these options, with about 63 known moons then compared with Uranus's 27.

A note on current figures: Saturn now has the most confirmed moons (over 140), but it is not among the options. Among A to E, Jupiter is clearly the answer.

Answer: B. Jupiter

Tip: Remember the giants: Jupiter and Saturn (gas giants) have the most moons, then Uranus and Neptune. The inner planets have almost none (Mercury 0, Venus 0, Earth 1, Mars 2). If only one giant appears among the options, pick it.
