How big is the Betelgeuse star?

383.4 million mi (887 R☉)Betelgeuse / Radius

How big is the Betelgeuse red giant?

about 767 million miles
Betelgeuse is about 10 million years old and is much larger than our Sun. Betelgeuse’s measurements are approximately 950 times larger than our Sun, with a diameter of about 767 million miles (about 1.2 billion km). It is 10-20 times more massive than our Sun and emits between 7,500 and 14,000 times as much energy.

How many solar diameters is Betelgeuse?

764 solar radii
Using new observational data from the space-based Solar Mass Ejection Imager and three different modeling techniques, astronomers have found that Betelgeuse, a red supergiant in the constellation of Orion, has a radius of about 764 solar radii, a mass between 16.5 and 19 solar masses, and is 548 light-years away.

How big is the Betelgeuse star compared to Earth?

Between small planets in the solar system and the biggest stars, the size difference is enormous, for example, the diameter of the star Betelgeuse is 141,863 times larger than the diameter of the Earth.

Which star is bigger Antares or Betelgeuse?

Betelgeuse is at an approximate 887 R☉ slightly larger than Antares A—though, “slightly” bigger here still means a difference in diameter of almost 5.57 million km.

What’s the diameter of UY Scuti?

What is the diameter of Canis Majoris in KM?

1.97578 billion kilometers
VY Canis Majoris has a diameter of 1.97578 billion kilometers. This is more than 1,000 times the diameter of our sun at 1.391 million km….

Why does Betelgeuse appear red?

The low temperature means that the star will appear orange-red in color. Betelgeuse emits almost 7,500 times as much energy as the Sun. The combination of size and temperature tells astronomers that the star is a kind of star called a red super giant. Red super giants are stars that are close to the end of their life.

How big is Betelgeuse really?

It is hard to grasp the size of Betelgeuse. It is large but it is not the largest star. Betelgeuse is 1.234 billion km or (767 million miles) wide. Now we know the Earth is only 149.67 million km or (93 million miles) from the Sun. To get the width of Earth’s orbit you would double that and add a million.

Is Betelgeuse a giant star?

Betelgeuse is a red giant star in the constellation Orion, one of the most familiar constellations in the night sky. Pronounced “beetlejuice”, the star is roughly 10 times bigger than our Sun in mass.

What if Betelgeuse goes supernova?

What if Betelgeuse goes supernova? If Betelgeuse were to go supernova, it would certainly be a prominent feature in the night sky of Earth . The consensus seems to be that, although Betelgeuse has become an unstable star, an irregular variable casting vast amounts of its plasma into space, it is not at imminent risk of going supernova.
