If you subscribe to the idea of a flat Earth, then you’d believe that no such thing happened, because the sun rotates in a circle around the sky. The Earth has yet again made a revolution about the sun. A previous version of this story included an incorrect planetary reference.If Earth were flat, you’d know it, because a lot of things would work differently. 16, 2022: The Earth is a sphere that is 93 million miles away from the sun. A previous version of this story cited an incorrect amount of time.Ĭlarification, Sept. 15, 2022: It would take the sun eight minutes to reach Earth traveling at a speed of 186,000 miles per second. We rate claims that the sun isn’t that far away, and rather under a dome, Pants on Fire!Ĭorrection Sept. The average distance is about 93 million miles. At their farthest, they’re 94.5 million miles away from each other. At their closest, Earth and the sun are 91.4 million miles apart, according to the California Institute of Technology. Scientists then use what they know about interplanetary distances to scale the distance between the Earth and the sun.īecause Earth doesn’t orbit the sun in a perfect circle, its distance from the sun changes during the year. To measure how far we are from the sun, it’s necessary to first find the relative distances between Earth and other planets, Pandian wrote. Humans have been able to use radar to measure interplanetary distances since 1961, transmitting a radar signal at a planet, or the moon, and measuring how long it takes for that radar echo to return. In 2016, astronomer Jagadheep Pandian broke down how we know the distance between the sun and Earth for Cornell University.
