Newton's constant of gravitation G is 6.67×10-11 in the system of units we use with mass in kilograms, length in meters, and time in seconds. The radius of Earth is approximately 6.378 ×106 m, and its mass is 5.97 × 1024 kg. With all this you can evaluate conservation of energy from Earth's surface and find an escape velocity of about 11.2 km/s from Now suppose we wanted to orbit a spacecraft in low Earth orbit just a few hundred...
