'''Regulus''', also known as '''Alpha Leonis''', is a quadruple star system located 77.5 light years away. It is the brightest star of the constellation [[Leo]]. In the night sky, with the unaided eye, it is seen as a single star with an apparent magnitude of 1.35. From our vantage point on the Earth, Regulus sits just off of the [[ecliptic]], causing it to be regularly occulted by the [[Moon]]. The other planets also cause occultations of the star from time to time, with the next occurrence to happen on October 1, 2044, by the planet [[Venus]].
