How did Alex Halley determine the orbit of 1P/Halley? I get that he used the mathematics of Kepler and Newton and all of that. I understand he used historical records to determine periodicity. What I don't get is how he was able to do what the ancients couldn't, and look at a moving object in the night sky and work out its orbit.
I predict this thread will be full of anons telling me about elliptical orbits and how the Chinese saw it in ancient times, etc. I'm asking for how an observation leads to the math itself.

he just did, okay?

>What I don't get is how he was able to do what the ancients couldn't
he was the first one to look at it after having been gifted kepler's laws
>>
Let me ask the question this way then: How do you observe an object or point of light moving in the night sky, and determine its orbit?
>>
>>16827149
use kepler's laws. get a degree in astronomy if you want to learn the details.

>>16827162
the credentialist underpinning of this statement offends me
>>
>>16827149
There are lots of websites. You find the coordibates on various nights and enter them and the website plots the orbits from there.
They probably have apps now, but I'm a PC user so idk.

It's not credentialist, astronomy actually has pretty high degree of hobbyism and all the stuff you need are a google search away. If you wanted to learn you would do it yourself based on the first part of that post that gives you the thing you need to use. The second part is because you don't want to do it yourself and want someone to spoon feed you for which degrees exist.

He didn't. The elliptical is an approximation. Obviously one side is fatter than the other. There are also resolution of the measurements. Basically he made a claim that is so unimportant nobody even cares to debunk it. Which is funny, because PHDs come out of the wordwork to bash flat earth. His work is less important than some schizotuber.

only 35 years until it comes back bros dont kys yet

With maths.
>>
>>16827233
Halley didn't have an app, back then. So how did he do it?
>>
>>16827794
Websites were before apps. But Halley likely used his local library.

Never mind, I asked an AI Emma to explain it to me.

This is a calculus, isn't it?

I suspect this is it right here; Determine one part of a parabola, and use a formula to determine the area of the entire thing

And here is where he does it. What the prophets of old could not do.
