Because our Sun is a lot closer. 93 million miles instead of 3.7 quadrillion. (3,762,239,880,000,000 miles)
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.
No. Betelgeuse has 950-1200 times the diameter of the Sun.
Yes, it has a radius about 1000 times the radius of the sun.
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.
Yes, Betelgeuse has a radius about 1200 times the size of the sun, and Antares is about 800 times the radius of the sun.
Betelgeuse is around 10 times greater in diameter than Rigel.
The radius of Betelgeuse is 1180 times the radius of our sun.
Betelgeuse is about 18 or 19 times the mass of our sun.
The circumference of Betelgeuse is about 1180 times the circumference of our sun.
The size of Betelgeuse is variable (it pulsates); plus, there are different estimates. But its diameter is approximately 900 times that of our Sun, which in turn is roughly 100 times the diameter of Earth (actually 109, but the data don't justify a very exact calculation), so Betelgeuse has roughly 900 x 100 = 90,000 times the DIAMETER of Earth; the ratio of volumes is that same number, cubed, or (after some rounding) about 700,000,000,000,000 times as much.
With a radius of over 1000 times our sun, the volume of Betelgeuse is over a billion times our sun. So, our sun could fit into Betelgeuse over a billion times.
No. The biggest star ever discovered is the VY Canis Majoris, a red hypergiant with a radius of easily 2000 times bigger than that of the Sun. That is more than twice the radius of Betelgeuse. Also, the mass of VY Canis Majoris is around twice that of Betelgeuse.
