Until now, the only celestial bodies whose cores have been measured have been the Earth and the Moon. To do
To use seismic data formeasuring the inner part of the planetary body, many measurements are required. Sensors can tell you where such waves start and end. They also provide data on how long it takes for a wave to travel through a given part of the planet. This allows you to calculate its density. Using this data, the researchers were able to measure the depth of the core-mantle boundary in many places, which allowed them to calculate the size of the core.Scientists estimate its radius to be from 1810 to 1860 km, which is about half the size of the Earth's core. This discovery is somewhat unexpected - previous studies have suggested that it will be much larger. New evidence suggests that the core should contain more light elements than previously thought.
The research team plans to discuss theirconclusions at the Conference on the Study of the Moon and Planets this year, which will be held virtually due to the pandemic. One of the scientists, Simon Stehler, provided a pre-recorded presentation for everyone. In the near future, the team intends to publish their results in a peer-reviewed journal.
