Description

Regulus -Alpha Leonis- is the brightest star in the Constellation of Leo. It is located 77.5 light-years from Earth and circulates on the path of the ecliptic, which allows its occultation (Venus in 1959, Asteroid 166 Rhodope in 2005).

Regulus is a system with at least four stars. Regulus A, the main star, is binary. it has two companions, B and C, visible on the image, who form a couple turning around each other in 2000 years. This pair orbits around its main star in around 130,000 years.

Leo 1 is a satellite dwarf galaxy of our Milky Way, located more than 800 000 light-years away from Earth. I could only have a blur that we can guess on the left of Regulus.

IC 591, also weakly visible in the image, is a lenticular galaxy.
