Using parallax to find distance to the moon

WebIf such a class of objects can be found, and if it can be calibrated, preferably by measuring the parallax of one such object within our own galaxy, we can calculate the distance to the galaxy by measuring the brightness of the object and applying the inverse square law. WebExpert Answer. 11. Astronomers often measure distances in parsecs. This term comes from the phrase "parallax arcsecond" because one parsec is defined to be the distance to a star whose parallax angle is one arcsecond. If we have a star whose parallax angle is 1/2 of an arcsecond, its distance is 2 parsecs. If the star has a parallax angle of 3 ... in building cell coverage https://megaprice.net
