<P> Satellite galaxies that orbit from 1,000 ly (310 pc) of the edge of the disc of the Milky Way Galaxy to the edge of the dark matter halo of the Milky Way at 980 × 10 ^ ly (300 kpc) from the center of the galaxy, are generally depleted in hydrogen gas compared to those that orbit more distantly . The reason is the dense hot gas halo of the Milky Way, which strips cold gas from the satellites . Satellites beyond that region still retain copious quantities of gas . </P> <P> The Milky Way's satellite galaxies include the following: </P> <Table> <Tr> <Th> Name </Th> <Th> Diameter (kpc) </Th> <Th> Distance (kpc) </Th> <Th> Absolute magnitude </Th> <Th> Type </Th> <Th> Discovered </Th> </Tr> <Tr> <Td> Large Magellanic Cloud </Td> <Td> </Td> <Td> 48.5 </Td> <Td> - 18.1 </Td> <Td> SBm </Td> <Td> prehistoric </Td> </Tr> <Tr> <Td> Sagittarius Dwarf </Td> <Td> 2.6 </Td> <Td> 20 </Td> <Td> - 13.5 </Td> <Td> </Td> <Td> </Td> </Tr> <Tr> <Td> Crater II </Td> <Td> </Td> <Td> 117.5 </Td> <Td> - 8.2 </Td> <Td> dSph </Td> <Td> 2016 </Td> </Tr> <Tr> <Td> Small Magellanic Cloud </Td> <Td> </Td> <Td> 61 </Td> <Td> - 16.8 </Td> <Td> Irr </Td> <Td> prehistoric </Td> </Tr> <Tr> <Td> Canes Venatici I </Td> <Td> </Td> <Td> 220 </Td> <Td> - 8.6 </Td> <Td> dSph </Td> <Td> 2006 </Td> </Tr> <Tr> <Td> Canis Major Dwarf </Td> <Td> 1.5 </Td> <Td> 8 </Td> <Td> </Td> <Td> Irr </Td> <Td> 2003 </Td> </Tr> <Tr> <Td> Boötes III </Td> <Td> 1.0 </Td> <Td> 46 </Td> <Td> </Td> <Td> dSph?
