(b) Space graveyard
Scientists were initially planning to push the Tiangong-1 satellite to Point Nemo. However, they could not do so as they lost control of it. China’s defunct Tiangong-1 space lab mostly broke up on re-entering the Earth’s atmosphere above the South Pacific.
Point Nemo, or “ocean point of inaccessibility,” is a region in the South Pacific that is the loneliest place on the planet. It is used as a graveyard for controlled re-entries and a place where space junk can be dropped safely.
Point Nemo, named after the submarine captain in Jules Verne’s classic science fiction novel 20,000 Leagues Under The Sea, is about 2,688 kilometers from the nearest land – Pitcairn Islands – which lies to the north of this point. Also, Motu Nui — one of the Easter Islands — lies to the northeast and Maher Island, part of Antarctica, to the south.
