Regulus in an event that only occurs once every 28 YEARS

A cosmic game of hide and seek will be visible to stargazers tonight when the moon aligns with three planets and one of the brightest stars visible from Earth.
Our planet’s natural orbital satellite will block Venus, Mars, Mercury and the star Regulus, in the Leo constellation, during a 24 hour period of occultations.
The cosmic clockwork in our solar system often sees the moon align with other celestial bodies, but this particular arrangement occurs just once every 28 years.
