Uranus is more . However, its radius is also much larger than Earth's (about 8.1 times that of Earth). All bodies accelerate in vacuum at the same rate, regardless of the masses or compositions of the bodies;[1] the measurement and analysis of these rates is known as gravimetry. Being that it takes the weight of an object on earth and converts it to Martian weight, the formula is Weight on Mars= (Weight on Earth/9.81m/s2) * 3.711m/s2. We have shown that the value of g on the Moon is 1/6th that of Earth, so an object on the Moon weighs only 1/6th as much as it would on Earth.
