All the forces acting on this planet are extraordinary.
Gravity, electromagnetism, weak nuclear forces, and strong nuclear forces.
The three main types of stress: compressional, tensional, and shear.
Gravity pull of the sun, moon, planet, comets -
Speed to maintain orbits:
the Earth rotates on its axis, hurtling us through space at nearly 1700 km/hr for someone on the equator.
The Earth spinning on its axis gives us a speed of just 0.5 km/s.
In order to keep us in our stable orbit where we are, we need to move at right around 30 km/s.
the Sun speeds around in an ellipse, making a complete revolution once every 220–250 million years or so. It’s estimated that our Sun’s speed is around 200–220 km/s
