A team of astronomers has uncovered an Earth-like planet orbiting a star located 4,000 light years away from the solar system, potentially offering insights into Earth's distant future. The rocky planet, about the same mass as Earth, revolves around a white dwarf in the constellation Sagittarius.

The discovery brings a glimmer of hope for Earth's survival when our sun enters its final stages. It suggests that Earth could potentially avoid being consumed by the expanding sun, opening up possibilities for human migration to the outer solar system, with moons such as Europa, Callisto, and Ganymede around Jupiter, or Enceladus near Saturn, becoming possible havens for future generations.
