Parallax calculation of stellar distance
WebFor this star, as we know that parallax is 6.55milliarcsecond where, p = 6.55 x 10 -3. To calculate the distance, apply the formula, d = 1/p = 1 / 6.55 x 10 -3. = 152.67parsecs. As … WebThe unit in which stellar distances are expressed by astronomers, the parsec, is the distance of a star whose parallax is 1″. This is equal to 206,265 times Earth ’s distance from the Sun, or approximately 30,000,000,000,000 km. When p is measured in seconds of arc and the distance d in parsecs, the simple relation d = 1/ p holds.
