Is Rigel bigger than Betelgeuse? Betelgeuse is a red supergiant — the largest class of stars. … Rigel is a blue supergiant. Like Betelgeuse, it is much bigger and heavier than the Sun. It’s surface is thousands of degrees hotter, however, so it shines blue-white.
Then, Which star is brighter Antares or Betelgeuse?
Both stars are typical massive M2 supergiant stars, 500-600 light years away. Betelgeuse is slightly brighter (V = 0.45), perhaps because it is slightly more luminous. … This means that, if Antares was where the sun is, we would be well inside it! Red Antares A has a hot blue companion Antares B, a B2.

Will Rigel become a black hole?
Rigel’s large mass (18 times that of the sun) will mean Rigel will become a black hole. When the star runs out of fuel, it can no longer push gravity back, and the core will collapse. After the core collapses on itself, gravity, pushing against the star, will compact the core until it is very small.
Is there a galaxy in Orion’s belt?

Which star has the greatest brightness?
Sirius, the brightest star, has an apparent magnitude of -1.46, while the faintest stars visible to the naked eye have magnitudes of about 6.
What’s the brightest thing in the universe?
The brightest object in the universe has been discovered, a quasar from when the universe was just 7 percent of its current age. The quasar, now known as PSO J352. 4034-15.3373 (P352-15 for short), was discovered 13 billion light-years away from Earth by the Very Long Baseline Array (VLBA) radio telescope.
Is Sirius the North Star?

What is Rigel’s fate?
Rigel is a blue supergiant that is the brightest star in the constellation Orion (the Hunter). Due to its measured size and brightness it is expected to end in a supernova one day.
Which star is most likely to become a black hole?
What kinds of stars end up as black holes? They are the natural consequence of the evolution of massive stars. Neutron stars have an upper mass limit of 2 to 3 solar masses. A collapsed object of greater mass will continue to collapse indefinitely, forming a black hole.
What does Orions belt represent?
Because Orion is on the celestial equator, Chandra adds, it is easy to see all over the world: “Ancient Indians saw the figure as a king who had been shot by an arrow (represented by the stars in Orion’s belt).

What is the coldest type of star?
M stars are the coldest stars and O stars are the hottest. The full system contains other types that are hard to find: W, R, N, and S. The closest star to the Earth, the sun, is a class G star.
What is the second star you see at night?
Venus can often be seen within a few hours after sunset or before sunrise as the brightest object in the sky (other than the moon). It looks like a very bright star. Venus is the brightest planet in the Solar System.
What’s the darkest thing in the Universe?
Black holes are the darkest things in our universe because they emit no light whatsoever in any wavelength.
Can a quasar blind you?
It turns out that’s not the sun at all, but the radiation and gamma-ray filled light coming from a quasar! So, in short, you’re in serious trouble. … Well, the thrown off material begins to glow from pressure and friction, resulting in the blinding light you’re seeing.
What does a quasar look like?
The term quasar originated as a contraction of “quasi-stellar [star-like] radio source”—because quasars were first identified during the 1950s as sources of radio-wave emission of unknown physical origin—and when identified in photographic images at visible wavelengths, they resembled faint, star-like points of light.
