Sidereal and synodic motion: Earth, Jupiter and Io
I would need help to understand and derive or relate synodic periods. I have been given the following relationship: $$ \frac{360}{\theta} = \frac{P_{jup}}{{P_{io}}} $$ where $P_{io}$ and $P_{jup}$ are ...

I'm trying to replicate Rømer's experiment but can't seem to get even close to the correct value for the speed of light
I am trying to replicate Rømer's experiment where he determined the speed of light by observing and measuring the eclipse timings of Io by Jupiter. I'm using Stellarium for this experiment and no ...

Turning Io into a electrical generator
Ok, so a while ago, I found out that Io's interaction with Jupiter's magnetic field produces around 3 million amperes at around 400,000 volts. if a hunk of rock can produce that much energy, that ...

If you stacked Jupiter and Saturn pole-to-pole (magnetically) on top of each other, would the magnetic force come close to the gravitational one?
The titular question should say it all. Let's assume they're essentially touching each other (so the distance between them is 0 based on their commonly stated radii). At that exact moment, how does ...

Can Jupiter turn into a star if it radiated off enough heat?
Since a star heats up when it radiates more heat (via gravitational compression), and since that's also how protostars turn into stars, I was wondering what are the chances of Jupiter reaching the ...

Why does Jupiter have so many moons?
The usual explanations one finds just say that Jupiter has a strong gravitational field, thereby being able to catch moons easier, and then they stop there. But this seems far from a satisfactory ...

What is the maximum flux of 1 GeV stably-trapped protons in Jupiter radiation belts?
And in which L-shell? This graph shows a flux of around 50 stably-trapped protons per m2 per sec on Earth, and I have read it's higher in Jupiter but I can't find the value. A source would be ...

What is the precise internal structure of Jupiter?
I've been trying to find out exactly where the layers of molecular hydrogen, and metallic hydrogen are precisely, inside Jupiter, in kilometres from the centre. Ideally with an error margin of 1-10kms....

How do I determine the exact distance from Jupiter to the Sun on a specific date?
I've recently needed to determine exactly how far Jupiter was from the Sun on April 25th 2018, when a Hubble image of Jupiter was taken. I'm a beginner in physics and Google searches lead me nowhere. ...

Is the radiation on IO's surface directional?
I know that magnetospheres redirect solar radiation into the poles of a planet, but since IO is in Jupiter's magnetosphere does that mean that solar radiation is redirected across the planets surface ...
