Earth Figures Earth’s orbit is elliptical and the distance from the sun varies from around 147 million kilometers to 152 million kilometers on any given year. Every star has a habitable zone that is affected by the size of the star and its intensity. The sun’s habitable zone is about 0.95 AU to 1.37 AU. An AU is the earth’s average distance from the sun, 93 million miles, therefore earth’s orbit could decrease by 4, 500, 000 miles or increase by 34, 000, 000 miles and still be in the habitable zone.
