Can you see the star Betelgeuse from Earth?
You can see Betelgeuse with the naked eye. Betelgeuse’s colour is due to the fact that it is an ageing ‘red supergiant’ star, over one billion kilometres in diameter (that’s nearly 1,000 times the size of our Sun).
Is Betelgeuse the closest star to Earth?
Betelgeuse is a supergiant star Betelgeuse is the nearest red supergiant star to Earth.
How long does it take for light from Betelgeuse to reach Earth?
430 years

| Object | Time for the Light to Reach Us |
|---|---|
| Sirius (brightest star in our sky) | 9 years |
| Betelgeuse (bright star) | 430 years |
| Orion Nebula | 1500 years |
| Andromeda Galaxy | 2.5 million years |
How distant is Betelgeuse?
548 light-years
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.
Is Betelgeuse in the Milky Way galaxy?
PARIS: Astronomers have managed to take pictures of Betelgeuse showing that the star, one of the brightest in the Milky Way, has been losing luminosity over recent months, the European Southern Observatory (ESO) said on Friday.

Rigel/Distance to Earth
How long does it take for sunlight to reach Earth in minutes?
8 minutes and 20 seconds
Sunlight travels at the speed of light. Photons emitted from the surface of the Sun need to travel across the vacuum of space to reach our eyes. The short answer is that it takes sunlight an average of 8 minutes and 20 seconds to travel from the Sun to the Earth.
How long would it take to get to Pluto at the speed of light?
4.6 hours
So let me give you some context. Light itself takes 4.6 hours to travel from the Earth to Pluto. If you wanted to send a signal to Pluto, it would take 4.6 hours for your transmission to reach Pluto, and then an additional 4.6 hours for their message to return to us. Let’s talk spacecraft.
