Article title: « La Terre possédait-elle des anneaux il y a 466 millions d’années? »
The article discusses a study that suggests the Earth may have had rings similar to Saturn’s around 466 million years ago. However, these rings would not have been composed of ice and rock but of meteorites. The evidence for this comes from traces of an element called iridium, which is rare on Earth but common in meteorites, found in rock formations from this time period. The rings would have only lasted for a short period of time before they collided with the Earth.
Answer:
Yes, according to a study, the Earth may have had rings made of meteorites around 466 million years ago. The evidence for this comes from traces of iridium found in rock formations from this time period.
