According to Kepler's laws of planetary motion, planetary orbits are in the shape of an ellipse with the Sun at one of the foci.
The Earth became a sphere due to a process called planetary differentiation, which involved the heavier materials sinking to the core and the lighter materials rising to the surface. This process, along with the force of gravity acting uniformly on the planet, helped shape the Earth into a sphere over time.
Answer this que What is the process by wich planetary features are formed? stion…
it reveals the true shape of a surface
The planetary surface or crust.
It is called an ellipse.
Johannes Kepler
Planets orbit in an ellipse.
Planetary orbits are usually in the shape of an ellipse.
They are usually an ellipse, which is a regular oval shape.
They are usually an ellipse, which is a regular oval shape.
In the context of planetary formation, gravity and density are related in that gravity pulls together materials of different densities to form planets. Higher density materials tend to sink towards the center of a forming planet due to gravity, while lower density materials remain closer to the surface. This process helps shape the overall structure and composition of a planet as it forms.
