What core temperature must be reached for nuclear fusion to begin, marking stellar ignition?
Answer
Around 27 million degrees
Stellar ignition occurs when the core temperature and pressure reach the critical threshold, stated to be around 27 million degrees, allowing hydrogen nuclei to fuse into helium.
