The international Space Station, including its solar panels, is about the size of a soccer field. When the sun reflects off it, it appears as a bright moving star in the evening sky, and takes about 6 minutes to move from horizon to horizon. If you were to hang a string from the ISS to the Earth, the string would be traveling along the Earths surface at 293 miles per MINUTE or 472 km per MINUTE. You can find out when the ISS will be passing over your area by going to http://www.heavens-above.co
