Solar System dynamics discussion thread

I even understood 10% of it, it was so well explained! Hahahahahaha :lol: I'm learning a lot right now while I make this so plase add me to the prehistoric group of people here. Ok so let me say that I have changed a lot of the previous post because I think I was falling into another missconception...

Solar System dynamics discussion thread

21371  I did try directly computing orbits with and without perturbation just to try to get some intuition for how the perturbation effect works.  For starters I assumed co-planar, circular orbits, and also that only Neptune perturbs Uranus and not vice versa (which probably matters very little). W...

Simulation Hypothesis Topic

22388 They would say that the astronomers methods are 'unfalsifiable'  from their viewpoint, simply because they do not understand them (having never studied physics, chemistry or astronomy in general). I have to agree with Watsisname here. I think the fact that something is important or not is not...

What exoplanet might reply us back?

A paper has been published that examines the Earth as an exoplanet from the context of transit detection methods from other stellar systems. So this is a little off-topic but I prefer to write this here since a new thread would be unnecessary in this case. The paper is called " Transit Visibil...

21605 Lagrange Points and Trojan Orbits Gravitational balance and stable configurations in rotating reference frames I've sort of returned form holidays now. Watsisname this is so so interesting and well explained I have no words for it. There are a lot of canonical explanations but all I've seen s...

Qr Bbpost Apparently I never posted my ISS solar transit photo here. Time to fix that.

Wooow HarbingerDawn that's an award winning level shot. Amazing, right in the center and without any motion blur. Just perfect.

22197 Whether or not we send targeted radio broadcasts to specific destinations does not matter. We have been telling the universe for over 100 years now that we are here! I'm curious as to how the radio power output of Earth has changed in those 100 years. Maybe that can tell us about how far thos...

Science and Astronomy Questions

21964 I calculated that I've spent just over a week airborne over the past 12 months covering a distance of about half a light second.  Does this also mean that I've travelled half a second further into the future than if I'd remained at home, or is the maths more complicated? Half a light second (...

Mathlogger did an excelent video recently about this and how is connected to Fourier series. qS4H6PEcCCA At the end of Geocentrism astronomers started to add epicycles on epicycles. This nested structure worked (and works still for the complex orbital perturbations we are able to measure today since...

Realistic shapes/maps of known Solar asteroids/comets

It looks like people is starting to refine 3D models for asteroid Ryugu (now been visited by Hayabusa2). This model was made by Roman Tkachenko. I've been unable to locate the actual model but I guess we will have the opportunity to see it in SE when a model based on better data arrives. 7-7xg4XAcIk

21469 I think in about 10-20 years someone will reply back. Look at this table . The closest arrival date for a targeted interstellar message is the Morimoto - Hirabayashi Message, which arrived to its destination, Altair , in 2017. Altair is located just 16.7 light years away. So a response could ...
