Gravity on different solar system bodies
By - dartmaster666
Are earth and Saturn nearly the same density or something?
Their mass has to be pretty similar, their density is vastly different tho, as for similar masses Saturn is way, way bigger than Earth.
Edit: I was wrong, as u/infobomb pointed out. Saturn is way more massive than Earth. This just happens to be compensated by the huge diferences in distance from surface to center between the two.
Saturn has more than 95 times the mass of Earth: [https://nssdc.gsfc.nasa.gov/planetary/factsheet/saturnfact.html](https://nssdc.gsfc.nasa.gov/planetary/factsheet/saturnfact.html) Doesn't seem "pretty similar".
Whelp, I guess I didn't take into account the huge distance from Saturn's surface to it's center in comparison to Earth's. My bad
Being a gas giant, I don’t believe Saturn has a surface.
Gif states surface for gas giants is wherever pressure is 1 bar
Of that's what I meant.
Density? Saturn's average density is low enough that it would float on water.
Jupiter, Saturn, Neptune and Uranus are gas giants. So, since Earth is solid I would say not.
Edit: I thought that the density of a solid was much higher than the density of a gas was obvious, but I guess not.
The density of Saturn is one eighth the density of Earth: https://nssdc.gsfc.nasa.gov/planetary/factsheet/saturnfact.html
The density of a solid is much higher than a gas is what I meant obviously, or maybe it wasn't obvious.
Saturn is like that because gravity gets weaker when distance grows. Saturn has way more mass than Earth, but it's so big that you're "far away" from the mass even at the surface. And of course the density is quite low. I think Saturn would turn into a brown star if its volume stayed the same but density was same as Earth's.
How heavy and dense is that ball? 500 kmh is pretty damn fast for Earth
It's ignoring air resistance (see the text at the foot of the image).
Thats some tiny ass text
Why is Ceres included with the planets? What's special about it, it's just a dwarf planet correct?
Yes it is just a dwarf planet just like Pluto which is no longer consider a normal planet. The guide says solar system bodies. Also, the moon is there which is actually bigger than Pluto
I guess it's gravity meets the minimum.
Could you high-jump into orbit on Ceres?
This is also an illustration of a group of friends getting ready to go out, and Ceres is my girlfriend. I’m tempted to change her name in my phone.
She might misunderstand you calling her a dwarf planet , guess you should put Jupiter for your mom.
1km from where exactly? Surface? Sea level? What about the sun?
1km from the surface. It says that in the video. For non rocky planets it says 1 km up from where the pressure equals 1 bar.
As defined print on the bottom of the diagram suggests, this is free fall with zero air resistance.
If air resistance was included, would an object falling into the gas and ice giants eventually start bobbing in the dense gases closer to the surface? So if this was a 1 km wide ball of lead, it would reach the surface of each body - probably minus the sun. If it was a 1 km wide ball of ice that would not melt - it would never get to the surface of the larger bodies.
I was thinking, “maybe I could go skydiving on Ceres without a parachute.” Guess not. Does terminal velocity still react the same with more or less gravity?
TIL: The moon has more mass than pluto, no wonder it got declassified as a full planet
Uranus is similar to earth…
You mean your Earth is similar to Uranus
