$\begingroup$ Mercury's density is 5.4 so it fits well with its neighbours. Still, it has the same surface gravity as the larger but less dense Mars. So I thought that maybe there are more general physical processes which tend to top out planetary solid surface gravity at about 1g. $\endgroup$ –
Not close. A 200 lbs man under that low a g force would several times lighter than a feather, you could lift a truck, in that g-force, with your pinky. You might be able to lift a 747. Now, heavy objects still have inertia, so you couldn't, for example, throw a truck like a baseball, but you could hold it up, against a gravity that low easily.
The strength of gravity on Mercury is about 38% of the gravity on Earth. This is due to Mercury's smaller mass and size compared to Earth. The Force of Gravity on Mercury results in an ...
Another gravity-related effect (although, as pointed out by Dieudonné, present only on our solar system between bodies that have very close orbits like the Earth-Moon and Sun-Mercury systems) is known as Tidal locking, or captured rotation.
Best Answer. This does seem odd. Mars, with a mass that is about twice the mass of Mercury, has about the same surface gravity. Mars' mass is about .107 the mass of earth, and the mass of Mercury ...
Mercury's mass are 3.3011e+23 kg and Mercury's mean radius are 2439.7 km. This results in a surface gravity of 3.7014 m/s² or 0.3774 g. Mercury's highest elevation is 2.78 mi (4.48 km) above what is considered the sea level. So I add these 4.48 km to the mean radius which results in 2444.18 km, thus the gravity would be 3.688 m/s² or 0.3761 g.
The gravity on Mercury is approximately 3.7 m/s^2, which would be equivalent to 3.7 Newtons of force acting on a 1-kilogram mass due to gravity on the surface of Mercury. The gravitational force ...
Best Answer. The acceleration of gravity on the surface of Mercury is 3.7 m/s2, compared to 9.8 m/s2 on. the surface of the earth. The force between Mercury and any mass there depends on the. size ...
Venus, Jupiter, and to a lesser extent, all the other planets, make Mercury's orbit precess by over 500 arcseconds per century. A key problem of the latter half of the 19th century was that the calculated precession of Mercury disagreed with its observed precession by 46 arcseconds per century. General relativity fully explains this apparent ...
Nevertheless, the observation that volcanoes on Mercury are rare is important itself. It means most eruptions on Mercury were somehow different from those that made volcanoes elsewhere in the solar system. We suggest that most eruptions on Mercury were too large and rapid, meaning that lava spread out to form plains, rather than building volcanoes.
