Regulus lies almost exactly on the Ecliptic, the apparent path
of the Sun through the sky. This means that, once each year, the Sun will
appear to pass directly in front of the star, an event which happens on or about the
22 August.
This blue dwarf star is slightly variable, but is always bright from an Earth-bound observer's
perspective, with an apparent magnitude varying around +1.3. Regulus is also notable for lying almost exactly on the line of the Ecliptic.
