Transcript of Regulus
Where will we go?
Regulus is a gigantic star that rotates rapidly, 77.5 light years away. This star is a blue/white color and if it spun 10% faster, it would literally fly apart! Regulus is the 21st brightest star in the Night's sky. It's a multiple star system with 2 pairs of 2 stars. Due to the fact that it rotates rapidly, the star can complete a full rotation in 15.9 hours (Earth time)! Lastly, Regulus pumps 350 times more energy than our sun, which
means it will die earlier.
On an HR Diagram:
As you can tell by the image, Regulus is in the Main sequence, very high in temperature 12,000 Kelvin, and quite bright (luminosity of 240 Suns)!
Stage In Life:
Regulus is in its Main Sequence currently.
It is a high mass star which means it won't live as long as our sun. Since Regulus is about 5 million years old, it is probably half way through its lifetime.
Composition of Elements:
You should check these out!
The charts below are organized by greatest to smallest in atoms in a percentage.
The best time to see Regulus in the Night's sky would be between the months of January - June because it is in a well-placed position.
Regulus has been nicknamed the heart of the Lion because in its constellation (Leo the Lion) It is in the position of the lion's heart. Coincidental, right?

Comparison to Our Sun:
Regulus wouldn't be the best for our life forms due to the fact that It is so large, not giving us a longer life of light. What is the point of moving 77.5 LIGHT YEARS AWAY if the star would blow up in the near future. Plus we would have to be far from the star to actually keep our shape, not die from the harmful radiation and to keep our eyesight. But we would have to be so far away that we wouldn't catch any heat that the star is producing. There would be a lot of precauutions to take to protect us from Regulus if we decided that was the star to move to; NASA would be better off researching another star for us.
There is a Character in the Harry Potter Series, Regulus Black (Sirius Black's Brother) who is named after the star Regulus.
