A near-perfect alignment will result either in a solar eclipse, or in a lunar eclipse.
You never know how long is sun going to live because the sun is extremely hot so the scientists cant look inside the core to find out how long did it live, when it was created, and how much longer is going to live.
I don't think there is anything we can do if the Sun were to die.
Scientists approximate the sun will die in about 10,000,000 years.
You can were glasses to protect your eyes from the sun then you can look safely at the sun

Scientists believe that the sun is around 4.6 billion years old. This age is determined through the study of the formation of the solar system, the analysis of age-dating techniques for rocks and meteorites, and the use of computer models.
just incase if it goes out
