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.
The closest star to Earth, other than the sun, is Alpha Centauri at some 4.4 light-years away. Scaling the Earth-sun distance at one inch places this star at 4.4 miles (7 km) distant. The red star in the center of this picture is Proxima Centauri, our sun's nearest neighbor among the stars.
