One of the oldest rocky planets discovered

[Eldorado 61,911]

The planet orbits the star TESS Object of Interest (TOI) 561, named for the ongoing NASA TESS planet hunting mission. TOI-561 belongs to a rare population of stars called the galactic thick disk. Thick disk stars are chemically distinct, with fewer trace heavy elements (and especially less iron) than typical stars of the Milky Way, suggesting they formed early, approximately 10 billion years ago.

They also have wandering motions that can lift them out of the galactic plane, providing an epic view of our own spiral galaxy.

"The rocky planet orbiting TOI-561 is one of the oldest rocky planets yet discovered. Its existence shows that the universe has been forming rocky planets almost since its inception 14 billion years ago," says Dr. Lauren Weiss, Beatrice Watson Parrent Postdoctoral Fellow at the IfA, and leader of the team that discovered the TOI-561 planetary system.

Good read!!

Hum how us that possible? If the planet was created after big bang beeing that old but reported to be relatively closer to Earth in astronomical terms, should make Earth older too. Besides hundreds of millions of years ago, that planet would have been much closer to Eart since we know due to universal expansion the distance between planets grows every year.

Galaxies crash into each other all the time. Expansion happens but after 10 billion years there are bound to be anomalies. I would love to see some observations of the star it orbits.
