There is a unit for measuring the distance from the earth to the sun known as an astronomical unit. This is 149,597,870,691Km (~93 million miles) plus or minus 30Km. You can use an astronomical unit to compare distances against the distance between the earth and sun e.g the distance between the sun and Mars is 1.52 AU.
So light crosses that distance in about a second. Meanwhile, the average distance from the Sun to the Earth is ~149,597,886 km (92,955,817 miles), which means that light only takes about 8 minutes to make that journey. Little wonder then why the speed of light is the metric used to determine astronomical distances. When we say a star like Proxima Centauri is 4.25 light years away, we are saying that it would take â traveling at a constant speed of 1.07 billion km per hour (670,616,629 mph) â about 4 years and 3 months to get there.
