Jakarta, CNBC Indonesia – The Sun’s remaining lifespan has been solved. The big star will go through stages before finally dying.
For information, the Sun is currently estimated to be 4.6 billion years old and the remaining 10 billion years. In about 5 billion years, the Sun will become a red giant and its core will shrink and its exterior will expand to Mars.
This means that during the process, the Earth will be swallowed by the Sun. However, it is possible that at that time human life would no longer exist because it is estimated that it would have been destroyed in about 1 billion years. Except to get out of the problem of the brightness of the Sun which is increasing 10% per one billion years.

The sun is also expected to become a planetary nebula, a glowing bubble of gas and dust. In 2018, an international team of astronomers believed this.
“When a star dies, it releases gas and dust known as a shroud into space. The shroud can reach half of the star’s mass. This will reveal a stellar core that at this point is still running, runs out of fuel, and then dies,” said one. author of the paper from the University of Manchester and astrophysicist Albert Ziljstar, quoted Tuesday (5/7/2022).
Ziljstar explains the hot core makes the outgoing envelope glow and occurs within 10 thousand years. That’s when the Nebula will be visible.
If the Sun dies and Earth is still around, Futuristic estimates humans may not notice it right away. It can take up to 8.5 minutes for humans to realize the Sun is no longer there and Earth has been traveling between stars at 18 miles per second.
The death of the Sun will have an impact on some of the objects that reflect its light, the Moon and the entire planet will turn dark.
The temperature on Earth also drops dramatically and freezes, although it can take millions of years for the planet to turn into a solid freeze. It is estimated that in its first week, the temperature on Earth will drop below 0 degrees Celsius. Next in the first year it drops to -100 degrees Celsius and to -240 degrees Celsius in a few million years.
When that happens, the Earth’s heat is still at work and humans will try to move closer there. The process of photosynthesis that requires the Sun will stop at that time, plants will be destroyed and most species will survive for a short time until they eventually perish.
