<P> A high Earth orbit is a geocentric orbit with an altitude entirely above that of a geosynchronous orbit (35,786 kilometres (22,236 mi)). The orbital periods of such orbits are greater than 24 hours, therefore satellites in such orbits have an apparent retrograde motion--that is, even if they are in a prograde orbit (90 °> inclination ≥ 0 °), their orbital velocity is lower than Earth's rotational speed, causing their ground track to move westward on Earth's surface . </P> <Table> <Tr> <Th> Name </Th> <Th> NSSDC id . </Th> <Th> Launch date </Th> <Th> Perigee </Th> <Th> Apogee </Th> <Th> Period </Th> <Th> Inclination </Th> </Tr> <Tr> <Td> Vela 1A </Td> <Td> 1963 - 039A </Td> <Td> 1963 - 10 - 17 </Td> <Td> 101,925 km </Td> <Td> 116,528 km </Td> <Td> 6,519 min </Td> <Td> 37.8 ° </Td> </Tr> <Tr> <Td> IBEX </Td> <Td> 2008 - 051A </Td> <Td> 2008 - 10 - 19 </Td> <Td> 61,941 km </Td> <Td> 290,906 km </Td> <Td> 12,963 min </Td> <Td> 16.9 ° </Td> </Tr> </Table> <Tr> <Th> Name </Th> <Th> NSSDC id . </Th> <Th> Launch date </Th> <Th> Perigee </Th> <Th> Apogee </Th> <Th> Period </Th> <Th> Inclination </Th> </Tr>
