In a few billion years give or take, so yeah, I suppose CORONA will be gone eventually and Trump will have been proven correct! So take that Libtard elitist snowflakes!

(65,010 posts)Would have to be around 10x larger (8-15 is the estimated range) for a star to go supernova.
But, your point is well taken.

(31,261 posts)It will destroy the Earth in around 6 billion years though. The way it will happen is through completion of Hydrogen fusion. Helium will begin to fuse in massive quantities and the Sun will start to swell over the 93 million miles between it and Earth. As Helium fusion gives way to fusion of larger elements, the Sun will complete the process of destroying Earth by consuming it. Many billions years after Earth is gone, the Sun will shrink, cool and for many billions of years become a white dwarf until everything in the Milky Way Galaxy is consumed by the end cycle of Sag A.

How Venus Turned Into Hell, and How the Earth Is Next
By Paul Sutter August 07, 2019
Earth is pretty nice. but it won't stay that way.
. . .
But four and a half billion years ago, our sun was different. It was smaller and dimmer. As stars like our sun age, they steadily grow brighter. So back then Venus was firmly planted in the habitable zone, the region of the solar system that can support liquid water on the surface of a planet without it being too hot or too cold.
But as the sun aged, that habitable zone steadily moved outward. And as Venus approached the inner edge of that zone, things started to go haywire.
As the temperatures rose on Venus, the oceans began to evaporate, dumping a lot of water vapor into the atmosphere. This water vapor was very good at trapping heat, which further increased the surface temperatures, which caused the oceans to evaporate even more, which caused even more water vapor to get in the atmosphere, which trapped even more heat, and so on and so on as things spiraled out of control.
Eventually, Venus became a runaway greenhouse with all the water dumped into the atmosphere trapping as much heat as possible, with the surface temperatures continuing to skyrocket.
