I am currently trying to make a game about Saturn and came across the xkcd article about the Interplanetary Cessna. Could their assessment of Saturn's atmosphere be incomplete in this context?
Saturn has a relatively dense atmosphere, even tho its mean molecular mass is just 2.07. At the...

I do not know if we have enough hobby astronomers here, but the above calls for a photo competition. But in any case, don't miss the opportunity if you're a stargazer!
I understand that there are a few of these still out there that have basically become Earth-crossing asteroids. It would seem that they wouldn't be as bright as the recent Chelyabinsk meteor.
Yup, they all appear together pre-dawn on March 18 to the SE. The planets hang out together for a week or so, while the Moon moves on.

Pardon the very naive question, but why does the atmosphere in these gas giants seem to have, from a distance, a very clear, sharp and distinctive boundary?
When one looks at Earth's atmosphere from space, it seems to have a fuzzy bluish boundary, gracefully vanishing into the black. I read...

Bad news for any slackers on Saturn: The days on the ringed planet are shorter than the number you'll find in most books--6 minutes briefer, to be exact. The faster spin drastically changes how scientists think Saturn's winds blow.
Full story: Science.

The radius of Saturn (from the center to just above the atmosphere) is 60,300 km (60300✕10^3 m), and its mass is 570✕10^24 kg. An object is launched straight up from just above the atmosphere of Saturn.

Hi all!
I took a couple of pictures of the Moon at night on 16 May (with an Olympus VR-340 compact digital camera, 10x optical zoom, 4x digital zoom). I used a very small tripod mounted on a microphone stand :biggrin:, and I decided to try out the camera on a star just for fun. First I tried on...
A quick question I hope:
What would I see from Earth if I sent a rocket to Saturn at nearly the speed of light?
If the rocket travels a million miles at a thousand miles an hour I will see it arrive in 1000 hours.
If the rocket travels at nearing the speed of light I won't see it arrive for...
Hey everyone. I was hoping I could get some assistance locating some material to research on the launch of the Saturn V rocket. I'm doing my honors project for calculus 1 on rocket launches, and I'm going to be focusing on the Saturn V.

Hi!
I've been trying to model the Saturn V's velocity using Tsiolkovsky's ideal rocket equation, and in the process, I think I may have made a mistake with regards to the specific impulse?

Hey, was just wondering, yesterday I was looking through my 10x50 binocular and used an app to locate Saturn. What I was seeing in the binocular was a burning ball (It was really bright compared to the stars.) and there was a sort of blue color around the bright ball. Would you think that was...

Has anyone in recent times reproduced the experiments of Kristian Birkeland, WRT to his Saturn effect using his terrella?
If so what were the conditions?

Hi
I came across this excellent forum :)
I am trying to figure out the solar wobble. When only looking at the Sun+Jupiter+Saturn, my intuitive interpretation is that the Sun will go faster/wobble more at Jupiter-Saturn-conjunction, and slower at oppositions. Is this correct?
If so, there...
A large storm has been studied since December 2010.

Quick question that maybe someone here could answer. I could probably dig up a bunch of math equations and answer it too, but I'm guessing someone here already has a good idea about the answer.

titan, a moon of saturn, has a 16 day orbital period and an orbital radius of 1,222,000 km. what is the mass of saturn?
my attempt:
t = 2*pi*r^(3/2)/sqrt(g*m)
t = 16 days = 1,382,400 s
r = 1,222,000/2 km = 611,000,000 m
1,382,400 = 2*pi*611,000,000^(3/2)/sqrt(6.67e-11*m) => m =...

Why the plane of the rings is vertical to the rotation axis of Saturn?
I don't think this is a coincidence, because the orbits of the 8 planets in our Solar System is roughly in a plane, and some galaxies are like a plate, so does the accretion plane of the black hole. But as we know...
