So the Moon is drifting away from Earth by 3.8 cm a year due to tidal interactions. With the Moon slowly receding from Earth, there will come a time when it no longer has sufficient angular size to cover the Sun completely. When will the last total solar eclipse occur?(when will the Moon's umbra no longer be able to project onto the Earth?)
