Sun has about 22 galactic orbits left, Earth far fewer
Original: 22 More Orbits for the Sun. Just 4–5 for Earth. https:// medium.com/@sensmedia.srl/22-m ore-orbits-for-the-sun-just-4-5-
An astronomy essay argues the Sun has roughly 22 more orbits to complete around the Milky Way before the end of its life, while Earth has only about 4–5 left in its habitable window before the Sun's evolution makes the planet unlivable. The piece is drawing attention from space science readers who find the comparison of solar versus planetary timelines striking.
Why now: The striking contrast between the Sun's remaining lifetime and Earth's remaining habitable window gives people a fresh, sobering perspective on cosmic timescales.
