Stellar Parallax - IB Physics

Stellar parallax is a method astronomers use for calculating the distance to nearby stars using their observations of how stars move in the night sky as the Earth orbits the sun. This lecture explains how we get the stellar parallax equation, how to use the equation to solve parallax problems, and how the unit of distance Parsec is related to the idea of stellar parallax.

All videos use this parallax angle but no one explained how to mesure it

Hey your videos are awesome, it would be great if you covered the Imaging option too

This is the best video so far. Very clearly explained with diagrams and exercise how it is actually calculated.

You nailed it mate.👍🏾

Thank you and best regards.

very clear and thorough explanation of a difficult concept

amazing really I have watched over 20 videos and its the first one I really understood

At 4:33 you said "this is the january angle of sight, and this is the july angle of sight" seeming to imply these values are just measured. How are these values typically measured? I'm imagining the deviation of the star being measured on a flat photograph. How does one get those two angle from a flat photograph deviation distance?

Hi Andy! Just wondering, is this playlist complete for option D? Does it include everything in the syllabus? Thank you!! :)

[shamelsinha]

Hey! Do you mind doing an Engineering Option too? It would be of tremendous help!

[Kielyn]

Excellent and explained in a simplified, easily understood manner

[iitncompany]

if its work then explain one simple example at home, take one object at one place inside your home then try to find the theta, may you find the theta ?

Also at millions kilometers everything will be looks like parallel to sun so this is wrong information.

[iitncompany]

if the star is not parallel to sun then ?
