How far is the sun from the earth?

Answer 1

1 AU.

The Earth is 1 AU away from the Sun at average. This distance is equal to 1.49 x #10^8# km. This is the Average distance also called the Semi-Major axis of the Earth's orbit because the orbit of Earth around the Sun no t a perfect circle so it is considered as an ellipse. So, sometimes the Earth is closer to the Sun , sometimes it is further away. At perihelion, the Earth is closest to the Sun at about 146 million km, whereas, at Aphelion, the Earth is furthest from the SUn at 152 million km.

The yearly variation in the Earth's elliptical orbit around the Sun causes the average distance between the Sun and Earth to be roughly 150 million kilometers, or 93 million miles.
