Hi. I'm just a hobbier of astronomy and have a question about elliptical orbit.
In Before, I had calculated the elipse of a planet successfully.
In this case, I wonder that can calculate velocity(red vector) using orbit time(or position on elipse).
Let me assume that we know orbit's semi-major...
Thanks for answer.
In additionally, I had been successfully calculated location of planet in a moment using given major axis and eccentricity from this article what you said.
However, cannot apply that topic to this problem. because that topic do not use any velocity but position and aphelion...
Hi. I'm just a hobbier of astronomy and have a question about elliptical orbit.
I wonder that can calculate elliptical orbit using just atitude(location) and velocity(vector).
Please look at my picture.
The blue dot is central body and green dot is my interesting body.
Let me assume mass of...
