# Does the Sun produce energy by using nuclear fusion?

Apr 15, 2018

Yes

#### Explanation:

The sun converts mass to energy by nuclear fusion. As a main sequence star, this is primarily by the fusion of hydrogen nuclei to form helium.

The most common reactions involve the following:

• ${\text{_1^1 H + ""_1^1H -> }}_{1}^{2} H + {p}^{+} + \nu$

• ${\text{_1^2H + ""_1^1H -> }}_{2}^{3} H e$

• ${\text{_2^3He + ""_2^3He -> ""_2^4He + 2 }}_{1}^{1} H + 2 {p}^{+}$
