Answer 1

The Sun generates energy through nuclear fusion of hydrogen into helium in its core, and it's the celestial body responsible for this process.

Step-by-step explanation:

The celestial body that generates energy deep in its core through the fusion of hydrogen into helium is the Sun. This process occurs in the Sun's core, where at a temperature of about 14 million kelvin, it fuses 620 million metric tons of hydrogen each second. The Sun is a main-sequence star and represents over 99% of the solar system's mass, shining by this very process of nuclear fusion, which is the prime energy producer in stars. Notably, once the Sun's hydrogen is spent, it will proceed to fuse helium and other heavier nuclei.
