Planet Survives Threat of Engulfment by Its Star
As stars like our sun swell in size with age, they can become large enough to engulf their inner planets. In May of this year, astronomers used the Zwicky Transient Facility, or ZTF, at Caltech's Palomar Observatory to catch one such aging star swallowing its planet whole . Our own sun is expected to similarly eat Mercury, Venus, and possibly Earth, in about 5 billion years. So, when a different group of scientists found a gas giant peacefully orbiting its aging star, they were confused. The star, a red giant called 8 UMi, or Baekdu, is at the ripe old age where it should have expanded in size beyond the orbit of the planet, entirely engulfing it.
