Deneb's solar wind causes it to lose mass at a rate of 0.8 millionth of a solar mass per year, a hundred thousand times the flow rate from the Sun. Name ...

Deneb is a bright, blue supergiant star, very young as stars go. Albireo, the bill of the swan, is actually two stars which show a spectacular amber and blue contrast.
