Is the parallax method still the one most widely used (for the relatively nearer stars at least)? More particularly, is it still the case that we take one measurement then wait six months until the Earth is on the other side of the sun and take a second measurement? Or has this been superseded by something else?
Also, with the parallax method we need to know the distance from Earth to Sun - so how did we first figure out how far away the Sun is?
Thanks in advance.
