How many miles is it to the sun from earth ?
As the Earth's orbit around the Sun is almost elliptical the distance actually varies throughout the year.
Earth is closest to the Sun at perihelion which is around $$3$$ January. It is furthest at aphelion in Early July.
To simplify things a unit called the Astronomic Unit, or AU, has been defined which is based on the distance between the Earth and the Sun. The AU is now an official standard which is exactly $$149,597,870,700$$ metres = $$92,955,807$$ miles.
