From Keplers discovery, scientists were also able to infer that the closer a satellite is to an object, the stronger the force of attraction, hence it must travel faster in order to maintain orbit. Relying on this formula, we are able to see that the velocity required for orbit is equal to the square root of the distance from the object to the center of the Earth times the acceleration due to gravity at that distance. So if we wanted to put a satellite in a circular orbit at 500 km above the surface (what scientists would call a Low Earth Orbit LEO), it would need a speed of ((6.67 x 10-11 * 6.0 x 1024)/(6900000))1/2 or 7615.77 m/s. So really, a satellites ability to maintain its orbit comes down to a balance between two factors: its velocity (or the speed at which it would travel in a straight line), and the gravitational pull between the satellite and the planet it orbits.

Explanation:
"The Turtle" is a poem by author Mary Oliver. The speaker in the poem talks of the beauty and effortlessness of turtle laying eggs in the sand. It's a sacred action, which the turtle itself cannot understand since the drive to do it does not come consciously. It is a purely instinctive drive, guided by nature. The speaker admires the turtle's determination and patience in completing the task while remaining unaware of itself as an individual. The turtle sees itself as the world, and the world as itself.
