A light-year is the distance light travels in a year. Therefore, if a certain star is "x" light-years from Earth, then it takes light "x" years to get fromthe star to us. Or the other way round.
It takes light 42.2 years for light from Capella to reach us
Capella is approximately 42.2 light-years away from Earth.
Betelgeuse is approximately 430 light years away from Earth, while Capella is about 42.9 light years away. Therefore, Betelgeuse is around 387.1 light years farther away from Capella.
Capella is about 42.2 light-years away from Earth, while Sirius is about 8.6 light-years away. Therefore, Capella is approximately 4.9 times larger in terms of distance from Earth than Sirius.
The nearest star to Earth in the Scorpius constellation is Antares, which is about 550 light years away. This means that light from Antares takes approximately 550 years to reach Earth.
It takes light 42.2 years for light from Capella to reach us
Capella is approximately 42.2 light-years away from Earth.
Betelgeuse is approximately 430 light years away from Earth, while Capella is about 42.9 light years away. Therefore, Betelgeuse is around 387.1 light years farther away from Capella.
Capella is the brightest star in the constellation Auriga.It has an apparent magnitude of +0.91.However Capella is a four star system split into two pairs of binary star systems. They just appear from Earth as a single star.
Capella is about 42.2 light-years away from Earth, while Sirius is about 8.6 light-years away. Therefore, Capella is approximately 4.9 times larger in terms of distance from Earth than Sirius.
The light takes about 640 years to reach Earth, as Betelgeuse (a red supergiant star) is about 640 light years from Earth.
6,300 years
It would take 100 Earth years for a signal to travel from a star located 100 light years away to reach Earth.
About 37 years.
If light leaves Proxima Centauri in 2020, it will take 4.3 years to reach Earth. Therefore, the light will arrive on Earth in the year 2024.
Polaris (North Star) is about 433 light years from us, so that is how long light will take to reach us.
The star won't normally "travel the 37 light-years to Earth". 37 light-years would most likely be the distance from the star to Earth; it takes light from the star 37 years to reach us. Please note that a light-year is a unit of distance; it is NOT a unit of time. To convert from light-years to kilometers, multiply the number of light-years by 9.5 x 1012.
