This video discusses various massive stars in the universe, highlighting their immense sizes compared to the sun. It mentions stars like CW Leonis, KW Sagittarius, Pistol Star, Sirius, Arturo Sul, Betelgeuse, and VY Canis Majoris. These stars are significantly larger than the sun and vary in characteristics, such as size, luminosity, and distance from Earth. The video emphasizes the vastness of the universe and our relatively small place within it.
1. The Sun is the biggest thing we can see from Earth, although it appears small because it is distant.
2. The Sun is 59 times bigger than Earth, with an estimated diameter of one million, three hundred and ninety-two thousand kilometers.
3. The Sun is just one of the many stars in our solar system.
4. There are thousands of other stars throughout the universe that are much bigger than the Sun.
5. One of the stars mentioned in the video is CW Leonis, located in the constellation Leo. It is probably the closest carbon star to Earth.
6. CW Leonis is hundreds of times bigger than the Sun, with a diameter of 700 million kilometers. Despite its size, it has a mass of only eight or nine times the mass of the Sun.
7. Another star mentioned is KW Sagittarius, a red hypergiant star located 9800 light years away from the Sun. It has a diameter 1,460 times larger than the Sun and emits 330 thousand times more light.
8. The star VY Canis Majoris, also known as Betelgeuse, is one of the biggest stars in the universe. It has a diameter of 2 billion and 300 million kilometers, making it 700 times larger than the Sun.
9. Despite its size, VY Canis Majoris has a mass of only 20 to 40 times greater than the mass of our Sun.
10. The star Betelgeuse, when placed in the place of our Sun, would swallow Jupiter and possibly other planets in our solar system.
11. The star Arturo, also known as Alpha Orionis, is one of the brightest stars in the Orion constellation. When it explodes, it will emit a very strong light that can be seen on Earth during the day.
12. The star Vy Canis Majoris, also known as Rho Cephei, is a red supergiant star with a radius 1700 times larger than our Sun.
13. Vy Canis Majoris is composed of hydrogen, helium, and other heavier elements, similar to the Sun.
14. Vy Canis Majoris is located 9,500 light years from Earth.
15. Vy Canis Majoris has a mass of only 20 to 40 times greater than the mass of our Sun.
