Its about 78 solar radii, which means that its diameter is 78 times larger than our own suns diameter of 1.392×106 .
so 78 x 1.392×106 = 1.086 x 108 km
or just over 108 million km
Betelgeuse is around 10 times greater in diameter than Rigel.
Betelgeuse is larger than Rigel. Betelgeuse is a red supergiant star with a diameter about 1,180 times that of the Sun, while Rigel is a blue supergiant with a diameter roughly 79 times that of the Sun.
Betelgeuse is larger in size than Rigel. Betelgeuse is a red supergiant star with a diameter about 800 times that of the Sun, while Rigel is a blue supergiant star with a diameter about 70 times that of the Sun.
Rigel: 71 solar radiiAldebaran: 44.2 solar radii.So Rigel is almost twice the size of Aldebaran.See related link for a pictorial of the difference (Section 5).
Rigel: 12100 K.Sun: 5778 K.
