Consider a hypothetical planetary system, within the Milky Way Galaxy, orbiting a central star known as Los. The star and planets, known collectively as the Ralos System, are to be found about two-thirds of the way out from the Galactic centre.
(Q)
One of the other planets in the Ralos System is Htrae, a relatively small, compact body, with an atmosphere, oceans of liquid water and a hard rocky crust that provides a surface for its inhabitants to live on. The inhabitants of Htrae have determined that their planet has an absolute age of 4.5 × 109 years. Explain the principle of a method they might have used to determine their planet’s age. PLEASE BE AS SPECIFIC SA POSS THANKS.
