Jakarta, CNBC Indonesia – The sun also has an age, it is currently estimated to have formed 4.6 billion years ago.
It is likely that the Sun’s remaining lifespan is about 10 billion years and there will be changes over time leading to the death of the massive star.
For example, in 5 billion years, the Sun will become a red giant. The core of the star is shrinking but the outside will expand into the orbit of Mars. That is, the Earth will be swallowed up in the process.

However, it is likely that when that happens, life on Earth will no longer exist.
Because, another prediction says human life only has 1 billion years left. Unless humans find a way to escape the brightness of the Sun, which is increasing 10% per billion years.
The sun is expected to become a planetary nebula, which is a glowing bubble of gas and dust.
Meanwhile, according to an international team of astronomers in 2018, the nebula became the corpse of the Sun. This point is said to be the most probable end of life.
When a star dies, it ejects gas and dust known as a shroud into space. The shroud can reach half the mass of the star.
“This would reveal a stellar core that at this point is still functioning, then runs out of fuel, then dies,” said University of Manchester co-author and astrophysicist Albert Ziljstar. Science AlertWednesday (3/8/2022).
Ziljstar says the hot core will make the outgoing envelope glow within 10,000 years. That’s when the Nebula will be visible.
The research team used data models that can predict the life cycles of various types of stars. It also knows the brightness of the Nebula which is related to the mass of different stars.
Meanwhile, when the Sun dies and the Earth is still around, page Futurism write down the possibility of humans not immediately aware.
It took them 8.5 minutes to realize the Sun had disappeared and at that time the Earth was still orbiting the Sun at 18.5 miles per second.
The death of the Sun will have an impact on a number of space objects that reflect sunlight, such as the Moon and the entire planet will turn dark. In addition, the temperature on Earth will drop to freezing point. However, it will take millions of years for the planet to turn completely frozen.
In the first week of the Sun’s death, the temperature on Earth will drop below 0 degrees. Next in the first year it changes down to -100 degrees and to -240 degrees in a few million years.
When that happens, geothermal heat is still felt and those who survive will also move closer to geothermal.
In addition, the process of photosynthesis that requires the sun will stop, plants will be destroyed and most species will survive for a short time until they are destroyed.
