Answer: 6.5 ly = 61,452,657,210,672 km
65 kilometers=6,500,000 centimeters
65 millimeters = 0.000065 kilometers
Approximately 65 light-years.
65 kilometers = 6,500,000 centimeters
569,400 hours in 65 years
65 years = 23,740.7 days.
It would take approximately 65 years to travel at the speed of light from Earth to Aldebaran, which is about 65 light-years away. However, currently, we do not have the technology to travel at the speed of light.
65 kilometers. 65,000 x 10^-3 = 65
6.5 kilometers = 4.03891275 miles.
The distance that light travels in a vacuum in one year, approximately 9.46 trillion kilometers or 5.88 trillion miles. Thus, the distance light can travel in 15 years is more than 88 trillion miles.
65 years
It would take 65 years for us on Earth to notice that the star has stopped giving off light energy, since light travels at the speed of light. This means that the light emitted by the star today will take 65 years to reach us, so we would only be able to detect the absence of its light after that time has passed.
