Current tidal theories cannot fully explain the observation of orbital decay in the system WASP-12b, a hot Jupiter whose decaying orbit will send it into its host star WASP-12 in a few million years.

Here is how long stranded NASA astronauts could survive on the International Space Station should the Earth suddenly be destroyed.

When these waves dissipate, the net result is the planet has lost orbital energy. That causes the planet's orbit to decay, bringing it closer to the star. Yet even this can't explain WASP-12 b's ...

“NASA has examined several options for decommissioning of the International Space Station, including disassembly and return to Earth, boosting to a higher orbit, natural orbital decay with random ...
