Can UY Scuti be seen from Earth?
UY Scuti is located in or galaxy the Milky Way, at about 5.219 light-years away from Earth. UY Scuti changes its brightness but it can be viewed from Earth as it is a pulsating star. It has an absolute magnitude of -6.2, UY Scuti is thus 340.000 times more luminous than our Sun.
Why do stars twinkle?
As light from a star races through our atmosphere, it bounces and bumps through the different layers, bending the light before you see it. Since the hot and cold layers of air keep moving, the bending of the light changes too, which causes the star’s appearance to wobble or twinkle.
How many years would it take to travel 4 light-years?
about 6,300 years
Last year, astronomers raised the possibility that our nearest neighbor, Proxima Centauri, has several potentially habitable exoplanets that could fit the bill. Proxima Centauri is 4.2 light-years from Earth, a distance that would take about 6,300 years to travel using current technology.
