A double star is two stars that are near each other. They are not necessarily physically related, so in this case their "size" is defined in an angular sense: how far apart are they? Since all stars have motion their separation, i.e., size is variable but it may take some time to change.
A pair which is physically associated is called a binary star. In this case, the size of the system can be defined by their orbit when it is known.

Albiero (a double star), but Deneb is its brightest star.
Sirius is a double star; the larger of the pair is twice the mass of the Sun and about 1.7 times the Sun's radius. So it would be about 740,000 miles radius.. and would be about five times the Sun's volume.

The double star coupon is when you play any game on Fantage and earn the double amount stars given. But you have to be a Premium Member to buy it.

It isn't. The sun is a star and there are others that are similar in size and temperature.
