The life of planets begins when dust grains around young stars coalesce in massive collisions. But defining the end of a planet is much more complicated than describing its formation.
According to Livescience; In the scientific world, the death of a planet is accepted as either its complete physical disintegration or the permanent change of habitable conditions on it. Looking at the example of Earth, the fate of our planet seems directly tied to the evolution of the Sun. Approximately 5 billion years later, when the Sun consumes its fuel and turns into a red giant, the Earth will first become uninhabitable as its oceans evaporate, and then it will face the danger of being swallowed by the expanding Sun or being thrown into space.
When we look at the universe in general, the lifespan of the Earth is actually quite short. Red dwarfs, which make up the majority of stars in space, can survive for trillions of years because they consume fuel much more slowly than the Sun. The rocky planets around these stars can maintain their internal heat and geological activity for tens of billions of years. This proves that there are worlds in the universe that will “survive” much longer than the Earth.
The ultimate fate of the planets is sometimes a huge collision, sometimes being thrown out of orbit and thrown into the endless darkness in the depths of the galaxy. The real truth that puts an end to the existence of a planet continues to remain hidden in theories about how the universe will come to an end.
