The Earth orbits the sun in an elliptical path. As a result, the planet's distance from the solar varies throughout the year. However, the usual distance between Earth and the Sun is approximately 93 million miles (150 million kilometers). This is also known as one celestial unit by scientists (AU).
The cosmos is vast, and researchers sometimes use astronomical units to convey how far celestial things are divided from one another. Jupiter, for example, circles the sun at a distance of about 5 AU.
