Hello students, this question is related to the methods to measure distance to astronomical objects.
00:05
The methods are humble, humble constant, radar measurements, rr raystars, fourth method is la supernova and parallax method.
01:18
We are asked to rank these methods in the rank of farther to closest distance measurement.
01:27
The humble constant method is used to measure the expansion of universe, the expansion of universe, like the distance from earth to the farthest, that is the farthest cosmic object.
02:09
For the radar measurements, radar measurements are basically used to determine the distance, the distance to planets within our solar system, within our solar system.
02:37
The rr raystar method, it is used to measure distances to globular, globular clusters or nearby and nearby galaxies.
03:23
Further, the type la supernova is used to measure the distance, distance to distant galaxies, galaxies...
