Betelgeuse is approximately 642 light-years away from Earth, and its diameter is about 1,000 times that of our Sun. If we assume a hypothetical spacecraft could travel at the speed of light, it would take about 642 years to reach Betelgeuse. However, if we consider the size of the star itself, circumnavigating it would take significantly longer, depending on the spacecraft's speed. Overall, the journey is currently beyond our technological capabilities and would take many lifetimes to complete.
The light takes about 640 years to reach Earth, as Betelgeuse (a red supergiant star) is about 640 light years from Earth.
it depends how far away the star is. it's not like we have the technology or anything anyway so....
Yes, black holes slowly evaporate after meeting critical mass or without any planets or star around it
Several thousand years.
There are currently no stars in the Orion constellation showing signs of going supernova. If a star in the Orion constellation were to go supernova, it would likely be visible to us on Earth given Orion's proximity.
Betelgeuse doesn't revolve around the sun. It is a star, even larger than the sun, and much too far away for the sun to have much effect on it.
The light takes about 640 years to reach Earth, as Betelgeuse (a red supergiant star) is about 640 light years from Earth.
Betelgeuse does not actually rotate like a solid body, as it is a supergiant star with an irregular shape due to its strong pulsations. It is estimated that Betelgeuse has a rotation period anywhere from tens to hundreds of years.
Betelgeuse is a red supergiant star located approximately 642 light-years away from Earth and has an estimated radius about 1,000 times that of the Sun. If we consider flying at a hypothetical speed of 500 miles per hour (the speed of a commercial jet), it would take over 1.2 million years just to reach Betelgeuse, and since the star is not a solid body to fly around, the concept of flying nonstop around it isn't applicable. In essence, it's far beyond human travel capabilities.
Since Betelgeuse is a nearby star (compared to the size of the galaxy, that is), you can assume that it takes about the same time as our Solar System to orbit the galaxy - approximately 240 million years.
First of all, Betelgeuse is 640 light-years away from Earth. So, even if a rover is sent to this star at the speed of light, it would take 640 years for it to get there. Second of all, once it reaches there, we would have to control the rover with radio signals. The signals would have to be extremely strong, and would take 640 years to get to the star. This is impossible and impractical. Third of all, Betelgeuse is a huge hot star. If a rover gets anywhere closer than a few million miles to that star, it would completely melt/vaporize. Fourth, as supergiant star, Betelgeuse has no solid surface; only tenuous gasses. So, no, a rover cannot be sent/land on the star Betelgeuse.
No one really knows, because no one has ever been to Betelgeuse. It would take much more time than getting to Pluto.
Betelgeuse is a red supergiant star about 640 light-years from Earth. So light from Betelgeuse takes 640 years to get here. Here's an interesting fact; the star Betelgeuse is probably near the end of its life, and may explode in a supernova explosion any time. Very massive stars like Betelgeuse live fast and die in under 100 million years, and Betelgeuse will probably go supernova within the next 10,000 years. This is like no time at all in cosmic terms, but in terms of a HUMAN lifetime, it probably will NOT happen while we're alive to see it. But it could. In fact, Betelgeuse might have exploded 500 years ago, and we wouldn't know it for another 140 years!

There is no other star that revolves around our sun. There are, however, many double and triple star systems in the universe, where the stars in the system revolve around each other.
Not sure about "that" star, but it would take about 3700 hours (0.42 years) to reach the sun, our nearest star. The journey to next nearest, Proxima Centauri, would take around 114000 years.
The North Star does not orbit the sun, nor do any of the stars. The North Star is its own star system several times more massive than the sun.
