Micul Nor al lui Magellan
Estimates on the peak column density of HVCs (1019 cm−2) and typical distances (1–15 kpc) yield a mass estimate of HVCs in the Milky Way in the range of 7.4x107 formula_1. If the Large Magellanic Cloud and the Small Magellanic Cloud are included, the total mass would increase by another 7x108 formula_1.
