If Aldebaran were to explode tonight then we will be able to see this explosion on the Earth in approximately 65 years. A light-year is a distance that light travels in one (1) year.
<h3>What is a light-year?</h3>
A light-year can be defined as a unit equal to the distance that light needs to travels in one (1) year on the Earth.
One light-year can be considered as a unit that equates to approx. 9.7 trillion kilometers (km) or 5.9 trillion miles.
In consequence, a light-year is a distance unit instead of a unit of time, and this unit was developed by Otto Ule.
