9:07 full moon- purnima
New moon- amavasya
21:24
Distance from Alpha centauri:- 4.376 light years
Distance from Proxima centauri:-
4.246 light years
Hence proxima centauri is nearest if the information is help full please like 😀
Correct 💯 information ℹ️
-_-
Sun is the nearest not proxima centauri
Proxima centauri is the 2nd nearest star from earth
@@ishucubing1553 yep that's right but he has said that the second nearest star is proxima centauri at 25:05
First nearest star is sun and second nearest star is proxima centauri😮

Sir I have a question..,... That jo apne the stars wale topic m sun and proxima century ka distance bataya h kya vo accurate h if yes to ise measure kaise Kia gya ??? Thank you!
By comparing the intrinsic brightness to the star's apparent brightness, we can get a good measure of the star's distance by applying the 1/r^2 rule. The 1/r^2 rule states that the apparent brightness of a light source is proportional to the square of its distance 😊
Sir it's my first class from pw and Now I know you are the best teacher in pw.
