This channel is so underrated these videos are awesome

I have a question. It is usually said that the giant planets, especially Jupiter, because of their gravity and mass have (or had) an influence on the whole solar system, like cleaning the orbits or protecting the inner planets from many objects like asteroids. It is even said that life exists on earth also because of this "protection". If their gravity is in fact not so great, how could it be?

Density isn’t mass over velocity but mass over volume

[___MAS___]

Gravity is a very fundamental force in physics. Gravity is measured in 1.0 G so that force is easy to categorize Earth as just a steady one (G) or you can call it 9.8 m/s2. However, if you go to space, or set foot in the moon, the gravity will be very different. 
Gravity is dependent on mass, from stars, planets, galaxies...etc, gravity seems to rely on just one thing. The mass can be categorized in three different ways, it’s size, mass, and density, and this is what gives the object gravity. When it comes to planets in our solar system, there is vary a size density and masses, and that for the strength of the gravity on the surfaces can vary dramatically.
As noticed the Earths gravity is 9.8 m/s2, this means that if you held an object and let go of it, it will accelerate towards the surface at a speed of 9.8 m/s every second from the free-fall.
Mercury is only around about third of the size of Earth. This makes Mercury the smallest and least massive planet in the solar system. However, it does have a high density, and this is just slightly lower than the Earth’s density. Mercury has a surface gravity of 3.7 m/s2.
What’s the gravity like in Venus? Venus is a very similar planet to Earth, and it’s often known as the Earth’s twin. It’s pretty much the same size as Earth, but a bit smaller. It again has a rad about the same density, but because of the lower density, the gravity changes. This comes out 8.87 m/s2. This means that the gravity on Venus is just lower than Earths’ at 0.91 G.
The gravity on Moon: The Moon is the only astronomical body where human beings are being able to test that gravity in person. The moon is a very small object at around 1, 737 KM in radius. It’s only about the size of the United States.  Because of its size and mass, it also has a low density. This means that the acceleration due to gravity on the surface of the Moon is about 1.625 m/s2, so the gravity is very low at 0.17 G. This gives a great reason why the astronauts on the Apollo missions would be jumping around like they’re on a trampoline. It also gave them a great excuse to experiment on the gravity of the moon, so you can do certain things on the surface of the moon that you can never do on the surface of the Earth.
What about Mars? It’s size, mass, and density are very small compared to our home planet. It’s a lot smaller than Earth, with this it comes with a lower density, and that for its gravity is lower as well at 3.72 m/s2. It’s actually closer to the gravity on the Moon than it’s is to Earth.
Jupiter is the giant of the solar system, it completely dwarfs the Earth and all of the planets. But because it’s mainly made out of gas, it has a much lower density, and therefore because of its considerable size, it doesn’t have a higher (G) than you’d expect. It only comes out 24.75 m/s2. This means the Jupiter’s gravity is only 2.53 G.
Like Jupiter, Saturn is a very similar planet. It’s the second largest planet in the solar system, and off course dwarfs all of the inner planets put together. It’s gravity is 10.44 m/s2, and surprisingly, it has near enough the same (G) as Earth does at 1.07 G.
So now it’s comes to the outer solar system, Uranus. It’s is the third largest planets in the solar system. And it’s just over four times the size of Earth. It’s only 8.69 m/s2, so that for its comes out at lower than 1 G at 0.87 G.
Finally, the furthest planet from the sun, Neptune. Neptune is the fourth largest planet, and it’s a very similar size to Uranus, not only in mass and size, but also in density. But it does have a higher gravity at 11.15 m/s2, this means that it actually goes higher than Earth at 1.14 G.
It’s doesn’t quite matter if you are in the surface of Mercury, the surface of Mars, or the clouds of Jupiter. Gravity basically determines that size, the mass, and density of all the planets and our sun. It also seems to figure out the formation of our solar system, and the orbits of the planets. Knowing how strong the gravity is on other planets, could help us understand more about gravity itself. Because understanding the gravity of a planet basics relies on three things, it’s mass, it’s size, and it’s density.

lol 1:06 apparently density = mass / velocity might wana check that

[SANKEniZUliCU]

I would like to taste 2x gravity....
That's my life goal

[bro-shamsulnubairi]

how to measure a weight/mass of a planet?

[jonbold]

Gravity is always directly proportional to the gradient of time dilation. But your calculations using mass, size and density will get you the correct answers.

[colepenny]

The gravity on the sun is “built different” sheeesh

[stephendoherty]

It also means lower gravity planets are easier for satellites to visit and move around as weight requires less effort

[scp-yrkv]

I told one kid that each planet/sun has a different gravity and he was bullying me after saying that I was stupid
He said that in space gravity is the same everywhere and he says that earth is different because of our atmosphere.

[peggyankney]

In the equation for density, the V stands for volume, not velocity

[tranceemerson]

I'd say that your presentation was a bit clunky for someone who's got a basic college background on this subject.

[fraser_mr]

and people assumed the gravity of mars would be the same as here on earth. that goes to show.. it would actually feel more like walking on the moon. it's actually quite small.

gravity of earth is just perfect for complex life... not too much and not too little.

[amyrenae]

What about the sun? What is its gravity?

[andrewau]

can we say that the density of a planet affects proportionally to the gravity it generates?

[tinak.]

It's sad that Neptune is smaller but has a stronger gravity than bloody Saturn.

[trumanhw]

*Mass x Radius (x gravitational constant) was what I'd wanted to show a friend graphically...*
*He literally **_meant_** "volume" -- he OBVIOUSLY knew the remedial formula. The almighty **_v_** is distracting*

[phiwenothwane]

so this means astronauts on Jupiter will be not comming Back?
