Welcome to your home planet and your neighbours in the solar system.

Distance from the Sun

AS you can see the distance, when measured in km or miles the distance soon gets very large, so we have another unit of measure we can use, the astronomical unit (Au). This is the mean distance of the Earth to the Sun. Therefore, as you get closer to the sun the distance is less than one, and as you get further away the higher the number.

ps, the Voyage spacecrafts are now over 148 Au from the Earth, having been travelling since 1977. It takes light more than 17 hours for light to get to the craft.
