WebWe adopt a distance modulus to the LMC (relative to which the more distant galaxies are measured) of µ 0 (LMC) = 18.50 ± 0.10 mag, or 50 kpc. New, revised distances are given for the 18 spiral galaxies for which Cepheids have been discovered as part of the Key Project, as well as for 13 additional galaxies with published Cepheid data. WebTouch and hold anywhere on the map that isn’t a place’s name or icon. A red pin appears. Select Measure distance . Move the map so that the black circle is on the next point you want to add. At the bottom right, tap Add point . At the bottom, you can find the total distance in miles (mi) and kilometers (km). Tip: You can add multiple points.
