Effect of planetary layer densities on trajectories of a satellite

Click For Summary
SUMMARY

The discussion centers on how the densities of planetary layers influence the trajectories of satellites and space probes. According to Cornell University's "Ask an Astronomer," the trajectory data allows scientists to calculate a planet's mass, while its visual size provides volume, enabling the determination of density. This method reveals insights into a planet's internal structure, particularly when surface materials differ from overall density, indicating layered compositions. The spherical nature of planets does not negate the impact of density profiles on gravitational fields.

PREREQUISITES
  • Understanding of gravitational physics

According to Cornell university's ask an astronomer site, we figure out the layers and their density of planets by checking the trajectory of a satellite /space probe or something like that, near the planets.
But planets are quite spherical. then their density profile shouldn't be effecting the gravitational field at all.

The trajectory gives us mass. The visual size gives us volume. Together this gives density. If the surface is ice, but the overall density is that of rock, that tells us a little something about the layering.
