Well Chilli I have your answer friend (grin)
300 000 kilometers, which equals seven times around the Earth.
Let's call this distance one light second. We can use this as a ruler to measure distances in space. Beyond the Sun and its planets we need a longer ruler, which is the distance light travels in one year. This is called a light year - it is 32 million times longer than a light second.

The earth itself Chilli is about 12000 kilometres! | Report
