Planet orbiting a dead star hints at Earth's destiny
Earth-Like Planet Discovered Orbiting an Alien Star. There's Just One Big Problem.
The red giant phase is pretty crazy. The star's outer atmosphere can expand to hundreds of times its initial size; some projections of the Sun's future – due to start becoming a red giant in about 5 billion years or so – predict it could grow as large as out to the orbit of Mars, engulfing Mercury, Venus, and Earth in the process.
Exoplanet orbiting dead star offers possible glimpse into Earth's future
"We do not currently have a consensus whether Earth could avoid being engulfed by the red giant sun in 6 billion years."
This exoplanet circling a dead star may mirror Earth's fate — if our planet survives a dying sun, that is
A newly discovered Earth-size world orbiting a dead white dwarf star gives scientists a hint of what the solar system may look like in billions of years.
Earth-like Planet Found Orbitting Dead Star Hints at Earth’s Survival Beyond the Sun
Astronomers have discovered an Earth-like planet orbiting a white dwarf star about 4,000 light-years away. This discovery offers a potential preview of Earth’s distant future as the Sun undergoes its own transformation into a white dwarf billions of years from now.
Existence of an Earth-like planet around a dead sun offers hope for our planet's ultimate survival
The discovery of an Earth-like planet 4,000 light years away in the Milky Way galaxy provides a preview of one possible fate for our planet billions of years in the future, when the sun has turned into a white dwarf,
