VY Canis Majoris is the largest known star and also one of the brightest. It is 1800-2100 solar radii in radius, or about 3 billion km in diameter. It is over 4,900 light-years from Earth. It is relatively unique when it comes to stars in that it is a single star, rather than multiple star systems, which would be more common for its size. VY Canis Majoris is so large, that if an airplane traveling 900 km/h were to circle it, it would take over 1100 years to make one journey!
Quando a noite mergulhar-me garras no peito, meu corpo queimará em cintilações e eu serei eterno no mundo.
