- On Earth, gravity gives weight to physical objects and causes the ocean tides. The force of Earth’s gravity is the result of the planets mass and density – 5.97237 × 1024 kg (1.31668×1025 lbs) and 5.514 g/cm 3, respectively.

With a mean radius of about 2,440 km and a mass of 3.30 × 1023 kg, Mercury is approximately 0.383 times the size of Earth and only 0.055 as massive. This makes Mercury the smallest and least massive planet in the solar system. However, thanks to its high density – a robust 5.427 g/cm3, which is just slightly lower than Earth's 5.514 g/cm3 – Mercury...
Venus is similar to Earth in many ways, which is why it is often referred to as "Earth's twin". With a mean radius of 4.6023×108 km2, a mass of 4.8675×1024 kg, and a density of 5.243 g/cm3, Venus is equivalent in size to 0.9499 Earths, 0.815 times as massive, and roughly 0.95 times as dense. Hence, it is no surprise why the gravity on Venus is very...
This is one astronomical body where human beings have been able to test out the affects of diminished gravity in person. Calculations based on its mean radius (1737 km), mass (7.3477 x 1022 kg), and density (3.3464 g/cm3), and the missions conducted by the Apollo astronauts, the surface gravity on the Moon has been measured to be 1.62 m/s2, or 0.16...
Mars is also similar to Earth in many key respects. However, when it comes to size, mass and density, Mars is comparatively small. In fact, its mean radius of 3.389 km is the equivalent of roughly 0.53 Earths, while its mass (6.4171×1023 kg) is just 0.107 Earths. Its density, meanwhile, is about 0.71 of Earths, coming in at a relatively modest 3.93...
Jupiter is the largest and most massive planet in the solar system. Its mean radius, at 69,911 ± 6 km, makes it 10.97 the times the size of Earth, while its mass (1.8986×1027 kg) is the equivalent of 317.8 Earths. But being a gas giant, Jupiter is naturally less dense than Earth and other terrestrial planets, with a mean density of 1.326 g/cm3. Wha...
Like Jupiter, Saturn is a huge gas giant that is significantly larger and more massive than Earth, but far less dense. In short, its mean radius is 58232±6 km (9.13 Earths), its mass is 5.6846×1026 kg (95.15 times as massive), and has a density of 0.687 g/cm3. As a result, its surface gravity (again, measured from the top of its clouds) is just sli...
With a mean radius of 25,360 km and a mass of 8.68 × 1025 kg, Uranus is approximately 4 times the size of Earth and 14.536 times as massive. However, as a gas giant, its density (1.27 g/cm3) is significantly lower than Earth's. Hence, why its surface gravity (measured from its cloud tops) is slightly weaker than Earth's – 8.69 m/s2, or 0.886 g.
With a mean radius of 24,622 ± 19 km and a mass of 1.0243×1026 kg, Neptune is the fourth largest planet in the solar system. All told, it is 3.86 times the size of Earth and 17 times as massive. But, being a gas giant, it has a low density of 1.638 g/cm3. All of this works out to a surface gravity of 11.15 m/s2 (or 1.14 g), which again is measured ...
Oct 11, 2024 · Gravity is what holds our world together. However, gravity isn’t the same everywhere on Earth. Gravity is slightly stronger over places with more mass underground than over places with less mass. NASA uses two spacecraft to measure these variations in Earth’s gravity.
The force that pulls things to the centre of Earth (and other planets) is called gravity. Gravity also holds Earth and the other planets in their orbits around the Sun.
The gravity of Earth, denoted by g, is the net acceleration that is imparted to objects due to the combined effect of gravitation (from mass distribution within Earth) and the centrifugal force (from the Earth's rotation).
Gravity. The natural phenomenon by which physical bodies appear to attract each other with a force proportional to their masses. It is most commonly experienced as the agent that gives weight to objects with mass and causes them to fall to the ground when dropped. The phenomenon of gravitation itself, however, is a byproduct of a more ...
Sep 25, 2024 · Gravity, in mechanics, is the universal force of attraction acting between all bodies of matter. It is by far the weakest force known in nature and thus plays no role in determining the internal properties of everyday matter.
