The evidence for the age of the Sphinx is not only that it is aligned with Leo rising for 10,500 BC, but also that the erosion on the body of the Sphinx can only be attributed to rainfall, which did not occur in the region much after 10,500 BC.
Proxima Centauri (from Latin, meaning nearest [star] of Centaurus) is a red dwarf, a small low-mass star, about 4.25 light-years from the Sun in the constellation of Centaurus.
Hubble image of Proxima Centauri, the closest star to the Sun. The simple answer is that the Sun is the closest star to Earth, about 93 million miles away, but that might not answer your question.
