Moon Orbit

Left is an interactive demonstration of the moon's change in apparent size over a typical month. The images here show 26 photos taken from June 5 to July1. Click the image and press the right arrow or spacebar or click the buttons that are shown. You can also show and hide rings that indicate the largest and smallest moon sizes from these images. Clicking a point just inside the orbit will show the corresponding photo. You can also right-click and choose Zoom in to examine the scale sizes of the Earth and Moon.

Image quality varies as a result of daily changes in atmospheric seeing conditions. Images near and at full moon were taken when the moon was near to the horizon, imparting a yellowish color. The shift of orientation results from setting up and taking down the telescope and tripod each day.
