Best ResponseYou've already chosen the best response.1A star in the sky is observed from earth to describe an elliptical path whose minor axis subtends an angle of 36". What angle does the star make with the ecliptic?

Best ResponseYou've already chosen the best response.0I have no idea how to measure angles in anything other than radians or degrees what are these 36''

Best ResponseYou've already chosen the best response.0also I don't even know what eccentricity of an ellipse is, so good luck

Best ResponseYou've already chosen the best response.0hmmm it looks related to the dot product of your planet's velocity vector and the star's light velocity vector

Best ResponseYou've already chosen the best response.1Yeah sort of, it has to do with relative velocity, but I guess I have to set it up differently, I have a few ideas

Best ResponseYou've already chosen the best response.0Alright so what's the elliptic?

Best ResponseYou've already chosen the best response.1Do you mean ecliptic :P

Best ResponseYou've already chosen the best response.0I don't know, sure why not, I just don't know what you're trying to do or what you're given.

Best ResponseYou've already chosen the best response.1The best way to think of the ecliptic is the ecliptic plane, which is the orbit of earth, I'll try to explain it with a drawing dw:1442806486190:dw

Best ResponseYou've already chosen the best response.1Yeah don't worry about it actually, I'll figure it out haha

Best ResponseYou've already chosen the best response.0LIke in my mind, the "abberation" of the star will be at a minimum since you will have stopped approaching and star to move away from it. So it will appear to blue shift then red shift eversoslightly at the angle you are looking for.

Best ResponseYou've already chosen the best response.0But I don't actually know any physics so that's just me blowing hot air

Best ResponseYou've already chosen the best response.1Haha, that's actually right, but this question is a bit weird, it's not as complicated, but that was one idea I have, to set it up with the star at rest and in motion and find the angle

Best ResponseYou've already chosen the best response.0dw:1442806619945:dw dot product = 0 but not sure if I am applying my idea of circles to ellipses in some way that doesn't exactly transfer over appropriately.

Best ResponseYou've already chosen the best response.1Ok the best way to explain stellar aberration is, as we observe the position of stars, there is a change in light relative velocity

Best ResponseYou've already chosen the best response.1I'll figure it out, thanks yo, but something cool, this is what was used to state that "ether" exists
