Betelgeuse is a red supergiant star located in the constellation of Orion, and it has a diameter estimated to be around 1,400 times that of our Sun. To determine how many Earths could fit inside Betelgeuse, we need to compare the sizes of the two objects.
The diameter of Earth is approximately 12,742 kilometers (7,918 miles). Let's assume we're comparing the diameter of Betelgeuse to the diameter of Earth. Since Betelgeuse has a diameter of around 1,400 times that of the Sun, which is about 1.4 million kilometers (870,000 miles), we can estimate that the diameter of Betelgeuse is approximately 1.4 million kilometers.
Now, dividing the diameter of Betelgeuse by the diameter of Earth, we get:
1.4 million kilometers / 12,742 kilometers ≈ 109,766 Earths.
Therefore, approximately 109,766 Earths could fit inside the diameter of Betelgeuse. It's important to note that this calculation assumes both objects are perfect spheres and does not take into account irregularities or variations in shape.
