• It is one of the largest known stars by solar radius and also one of the most luminous of its type.
• It is approximately 1,420 ± 120 solar radii[8] (equal to a diameter of 13.2astronomical units, or about 1,976,640,000 kilometres (1.22823×109 mi)), and about 1.2 kiloparsecs (3,900 light-years) distant from Earth.
• VY CMa is a single star categorized as a semiregular variable and has an estimated period of 2,000 days. It has an average density of 5 to 10 mg/m3.
• The first known recorded observation of VY Canis Majoris is in the star catalogue of Jérôme Lalande, on 7 March 1801, which lists VY CMa as a 7th magnitude star.
• This star has a diameter of about 2,800,000,000 km. Can you imagine the size of this star?
• Think of a passenger plane airplane flying along the surface of this star at 900 km/hr… it would take 1100 years to circle it one time! How interesting this is?
