How far is the Earth from the sun?
gpt
The distance from the Earth to the sun is not constant but changes throughout the year. This is because of the Earth's orbit, which is oval-shaped, also known as an ellipse, which brings about this difference. However, scientists have established that this distance is about 93 million miles (150 million kilometers), also known as one astronomical unit(AU).
