  7. What would happen if Regulus replaced our Sun? “If Regulus replaced our Sun we would be doomed.” We would no longer have and atmosphere and the Earth’s ocean would start to boil! The Earth would literally bake under the star’s heat!

  9. Size Regulus has a mass of 3.4M and a radius of 3.5R

  10. Age Regulus is 50 million years old!!

  11. Life Span Regulus Regulus’s full life span is about 100 million years (not a very long time). After it starts to cool down is will become a supergiant and might explode and cause a supernova or a neutron star.

  12. Regulus How Far Away it is Regulus is 77-light years away!

  13. Double Star?? Regulus is actually a double star. It is about “100 times as far from Regulus as Pluto is from the Sun” Double Star-”a set of two or more stars that appear next to each other”
