When will the sun be destroyed? When the sun is destroyed, will the earth be destroyed? So where should mankind go?

For a star like the sun, the period of the main sequence star is generally more than 7 billion years, and now the sun still has 5 billion years for human development, provided that we don't destroy ourselves. When the sun is destroyed, there will be a supernova explosion and huge energy will blow across the earth. If human beings will not be destroyed after 100 years, then according to the current situation and speed of scientific and technological development, interstellar migration can be completely realized.

I don't know about the planet you saw on the news, but on February 5th, NASA issued a statement, 20 1 165438, announcing the confirmation of the first earth-like livable planet outside our solar system through the Kepler mission. The surface temperature of this planet is about 70 degrees Fahrenheit (equivalent to 2 1 celsius), which is very suitable for living. In addition, there may be liquid water on this planet, which is regarded by scientists as a key indicator of life. This planet, named Kepler -22b, is about 600 light years away from the Earth and its volume is 2.4 times that of the Earth. It is the planet closest to the shape of the earth in size and orbit, and it orbits a sun-like star once every 290 days, just as the earth orbits the sun.
