Best ResponseYou've already chosen the best response.0A couple of different ways, depending on the level of accuracy you're looking for. Observing the redshift of its galaxy and then using Hubble's law, or using optical parallax, or determining its size by other means and then calculating its distance by measuring its brightness are all possibilities.

Best ResponseYou've already chosen the best response.0Mostly by the amount of doppler redshift. Sometimes the starlight undergoes some absorption on its path (dust, u know is everywhere) , if we know the amount of absorption per distance  it is an additional clue

Best ResponseYou've already chosen the best response.0as mentioned by mayank ... we can measure the nearby stars as : dw:1346830698728:dw

Best ResponseYou've already chosen the best response.0There are more options but the one that I know is already used in an answer above by mathslover. It's been measured with parallax, two measurement of the exact position of the star in the sky, 6 months apart (one side and from the other side of the earth). With more distant stars you should measure the brightness, I think.

Best ResponseYou've already chosen the best response.0Sorry mr. @muhammad9t5 , YOU ARE MISTAKEN YOURSELF and MISLEAD OTHERS. NEVER HAS ANY COSMIC OBJECT HAS BEEN MEASURED BY ITS GRAVITY. 1 IT IS USUALLY IMPOSSIBLE TO SEPARATE ITS GRAVITY FROM OTHER FORCES (GRAVITATIONAL or other 2 FOR STARS  IT WILL NEVER BE POSSIBLE BECAUSE IT IS TOO WEAK. I suggest you think in terms of reality, real physics and not overfertile imagination....

Best ResponseYou've already chosen the best response.0Hmmm, ok but what about the ionosphere? How do we know how far the two viewpoints are from each other?
