A book I read

Yesterday I read a very interesting book called space facts.
You can learn many interesting facts about planets like 'absolute vs apparent' for magnitude.
It turns out that the brightest star is 'Sirius' and some other stars are 'Regim' and the 'Sun'.
The higher the number for the magnitude, the fainter it is, and the lower the number, the brighter
the star's magnitude. The star: 'Sirius' has a whopping magnitude level of -6.7! You would go blind
if you look at that! You can also learn about the distance of planets from the sun measured in 'ly'
(Light Years). The book that I read has all the facts you need to know about space.
