How many years until the sun will explode?
The Sun does not have enough mass to explode as a supernova. Instead the Sun is expected to turn into a red giant in about 5 billion years. As a red giant, the Sun will grow so large that it will engulf Mercury, Venus, and probably Earth. But that's very far into the future!
The sun will engulf the Earth in about 5 to 7.5 billion years.
