The average distance between the sun and earth is approximately 93 million miles, or 149.6 million kilometers. This is also known as one astronomical unit (AU).
Scientists use a variety of methods to measure the distance between the sun and earth, including triangulation, radar, and parallax. These methods involve using mathematical equations and measurements of angles to calculate the distance.
Yes, the distance between the sun and earth changes slightly throughout the year due to the elliptical shape of the earth's orbit. The closest point in the orbit is called perihelion, and the farthest point is called aphelion. However, the average distance remains constant.
Light from the sun travels at a speed of approximately 186,282 miles per second (299,792 kilometers per second). This means it takes about 8 minutes and 20 seconds for light from the sun to reach earth.
The distance between the sun and earth is crucial for life on our planet. It determines the amount of sunlight and heat that reaches earth, which is necessary for photosynthesis and regulating the earth's climate. If the distance were to change significantly, it could have drastic effects on the conditions necessary for life to exist on earth.
