Summary:
- The article discusses the discovery of a rocky planet orbiting a white dwarf star, which is the remnant of a Sun-like star after it has exhausted its fuel and shed its outer layers.
- The planet, known as WD 1856+534 b, is approximately the size of Earth and orbits its host star every 34 hours, making it one of the closest exoplanets to a white dwarf.
- This discovery provides insights into the future of our own solar system, as the Sun will eventually become a white dwarf, and the Earth may continue to exist in a similar configuration around the Sun's remnant.
