A ROCKY «Super-Earth» planet has been spotted orbiting one of the Milky Way galaxy’s oldest stars.
Astronomers in Hawaii say the distant world is one and a half times the size of Earth, but takes just half the time to orbit its star.
That’s due to the close proximity between the two, which also makes the planet extremely hot at its surface.
In a study published this week, scientists estimate that the newly found planet, which orbits the star TOI-561, is an astonishing 10billion years old.
That’s more than twice as old as the Solar System, and nearly as ancient as the Universe itself.
«The rocky planet orbiting TOI-561 is one of the oldest rocky planets yet discovered,» said study lead author Dr Lauren Weiss.
