Inner planets are rocky thanks to their proximity to the sun. The heat emitted from these giant stars means that only materials with the highest melting points can survive, such as metals and rocks. These materials collide and join to form the base of a rocky planet. Continue reading to discover how these rocky clumps … Read more

Artificial satellites, on the other hand, are manually placed in specific regions of space to orbit Earth, Saturn, Jupiter, etc. to deliver services, whether images, telecommunication, or weather reports for scientific and recreational use. For a … Read more
