Zera renyeredzi imwe neimwe muMilky Way rinogona kuyerwa nekuyera kuwanda kwezvinhu zvinogara kwenguva refu zvine radioactive se thorium-232 uye uranium-238, ipapo kuenzanisa mhedzisiro nekufungidzirwa kwehuwandu hwavo hwepakutanga, nzira inonzi nucleocosmochronology. Izvi zvinopa kukosha kweanenge 12.5 3 mabhiriyoni emakore e CS 31082-001 uye 13.8 4 mabhiriyoni emakore eBD 17 3248. Kana chena chena chikaumbwa, inotanga kutonhora uye tembiricha yepasi inogara ichidonha. Nekuyera tembiricha yeaya madiki machena machena machena uye nekuzvienzanisa nezera ravo rinotarisirwa, tembiricha yekutanga inogona kuyerwa. Nekuyera uku kwezera kwenyeredzi imwe neimwe muMilky Way, zera rekare rinogona kuyerwa pa1523-01, wobva uchienzanisa mhedzisiro nezvakafungidzirwa kuyerwa  <response>: Makore ane mabhiriyoni 13,2
