How long will Earth exist

Scientists estimate that Earth could remain habitable for about 1 billion more years before the Sun’s increasing brightness makes the planet too hot for complex life. In around 5 billion years, the Sun is expected to expand into a red giant, potentially engulfing Earth or leaving it as a scorched, lifeless world. While Earth’s final fate is billions of years away, these predictions offer a fascinating glimpse into the future of our Solar System.
