WebJun 23, 2024 · The gravitational pull felt by a satellite is stronger when it orbits a very massive planet than when it orbits a planet of smaller mass. Note that what counts is the mass of the planet—not its radius—as the distance is measured to the center of the planet. WebMar 31, 2024 · We launch satellites and spacecraft into space by putting them on rockets carrying tons of propellants. The propellants give the rocket enough energy to boost away from Earth’s surface. Because of the pull of Earth’s gravity, largest, heaviest spacecraft need the biggest rockets and the most propellent. The GRACE Follow-On spacecraft ...
