What happened to Earth’s second Sun?
Some researchers believe that the star has already exploded, but earthlings do not yet see this glow, since it takes more than 400 years for the energy from the explosion to overcome the distance to the Sun. The outbreak of the second Sun for earthlings was announced by seismologists in the near future.

The parent stars are smaller than our sun. One is 69 percent the mass of the sun and the other only 20 percent.
Could there have been life on Earth if there were two suns?
