Betelgeuse is a red supergiant, and one of the largest and most luminous stars known, but not the largest - see related question.
It has a radius 936 times larger than our own Sun. If our Sun was replaced by Betelgeuse it's outer edge would extend between the orbits of Mars and Jupiter.
The Star is about 1,000 times larger than our Sun.
That puts it's radius at about 650,988,000 km (about 405 million miles).
See related link for a pictorial of the size difference.

Relatively large. It is twice the size of the suns solar system.
Betelgeuse is very big because is formed as a large star, and later it expanded even more as it ages, this creates its current size.
Betelgeuse is much larger than Rigel. Betelgeuse has a radius about 15 times the radius of Rigel, and a volume of about 3500 times Rigel.
It ia 250 times as big as the sun
Betelgeuse is about 1,180 times larger the Sun. So Betelgeuse is about 128,620 times bigger than Earth. So as a rough approximation about 2,127,774,087,928,000 Earths could fit into Betelgeuse. That's 2 quadrillion.
Betelgeuse is bright because it is a huge star known as a red supergiant. If it was where our sun was, it would be big enough to extend out beyond the planet Mars.

Betelgeuse is a large cool star
Big
Betelgeuse is bright because it is a huge star known as a red supergiant. If it was where our sun was, it would be big enough to extend out beyond the planet Mars.
super giants are a very very big star
In general yes because Betelgeuse is only a single star, albeit a big one. Nebulae are huge clouds of gas within which stars form
The star Betelgeuse is estimated to be about 1000 times the diameter of the Sun.If you put Betelgeuse where the Sun is; the planets Mercury, Venus, Earth and Mars would all be inside the star.

No. Betelgeuse does not affect us.
