How many light years from the earth is the sun?
a It's inconvenient to express a distance this short (!) in
light-years since it only takes light about 8 minutes to go that
far. The average distance from the Earth to the Sun is 150 million
km. Keep in mind that this is just an average. In reality, the
Earth's orbit around the Sun is elliptical. This means that it
follows the path of an ellipse around the Sun, and not a perfect
circle. When the Earth is at its closest point to the Sun, which
astronomers call perihelion, it's only 147 million km. And when the
Earth is at its furthest point from the Sun, astronomers call this
aphelion. At this point, Earth is 152 million km from the Sun.
