Which of the following celestial bodies contains abundant quantities of Helium - 3 a potential source of energy?

Options

A. Earth
B. Moon
C. Venus
D. Saturn

Answer

To determine which celestial body contains abundant quantities of Helium-3, a potential source of energy, we can follow these steps:

### Step 1: Understand Helium-3
Helium-3 is an isotope of helium. Isotopes are variants of a chemical element that have the same number of protons (atomic number) but different numbers of neutrons, leading to different mass numbers.

### Step 2: Identify Celestial Bodies
We need to consider the celestial bodies that are known to have Helium-3. The options typically include the Moon, Mars, and other planets or celestial bodies.

### Step 3: Research the Moon
The Moon is known to be bombarded by solar wind, which contains Helium-3. This means that the Moon has accumulated significant amounts of Helium-3 over time.

### Step 4: Confirm the Source
The solar wind is a stream of charged particles released from the upper atmosphere of the Sun. When these particles hit the Moon's surface, they deposit Helium-3, making the Moon a rich source of this isotope.

### Step 5: Conclusion
Based on the information gathered, the celestial body that contains abundant quantities of Helium-3 is the Moon.

### Final Answer
The answer is: **Moon** (Option 2).
