TL;DR Summary: . I need to find the location of following bodies MMR with Jupiter: 4:1, 3:1, with the help of Keplers third law.Keplers third law: , where P is the orbital period in Earth years, a= semi major axis in AU. For Jupiter: Pj = years. Now my question is, to find the location of...

So I have a few questions regarding the above task. I will use this equation to get the results for the different planets: Questions: So in the equation density p= mass of proton x proton density of the solar wind x 1000 000 (conversion between kgcm^-3 to kgm^-3) x 1/r^2 (I assume that I...

So in the equation density p= mass of proton x proton density of the solar wind x 1000 000 (conversion between kgcm^-3 to kgm^-3). B = M/r^3 where M= magnetic dipole of the planet in question, r= radius of the planet in question. μ0= 4pi x 10^-7 Vs/Am [magnetic permiability of free space] u=...

Yes correct, my bad!

Are you sure about u0? Because it seems it should be 4pi * 10^-7 as it is the magnetic permiability of free space: http://www.sp.ph.imperial.ac.uk/~mkd/AdvancedOption3solutions.pdf

Alright, could you help me understand what the signs in the denominator stands for. What is the B in the numerator? I assume the last term in the denominator is the solar wind velocity, the middle term pressure? And the u0 term is what?

Here are both equations mentioned in the slides.

So if you want realistic values, is it the second equation to be used? Because both give different results

These equations are coming from lecture slides.

Hello, Lets say you need to calculate the location of the magnetopause subsolar point on earth and you only have this information: > Solar wind proton number density: 10 cm−3 > Solar wind speed: 700 km s−1 Chapman_ferraro equations: What is the difference between the above chapman-ferraro...

Hi, so I have no clue how to solve this problem but I started off by rewriting the issue as a dot product to find the angle. So; cos(θ)= RSC⋅RSun / ∣RSC∣⋅∣RSun∣ Where Rsc = space crafts position vector. Rsun is the Suns position vector. ∣RSC∣ is the length of the spacecrafts position...

Thanks! Which forum should I post for help on astrophysics/space engineering topics? Is it Homework help --> engineering or engieering --> aerospace engineering?
