I am so glad i watched this video instead of glossing over it fast. It was very helpful bc you were calm etc. Thank you!

You did a great job at breaking down all the information. Most other videos were either very confusing, or spoken with a thick Indian accent. 10/10

Thank you for the video. How have you derived the equation d=1/p?

[shanegorrie]

Thank you for video, it really cleared everything up for my astronomy test today😊

[kleinzak]

Best explanation with an example as well. Bravo and THANK YOU! Good job!!!!

[filonowy]

Very good explanation. I finally understand that. Thank you!

do we need to memorise the conversion from AU to METERS?

[purpledoo]

Does someone know how to measure the parallax angle from the apparent shift of the star from the background??? I can't find this info anywhere...

[generationx-max]

May I ask why did you assign the parallax angle with 1 arc second? Why not 2 arcsecond s or 3 or 4 or 5 arcseconds?

Hi, thank you for your lovely video, just double check, the parallax is the name of the angle and it measured in arc-second, and parsec is the unit of the distance between the sun and nearby star ? Do you know does OCR exam board need to remember how to convert A.U. to meter? because I don't think it is in the formula booklet. Thank you so much !
