There was a total solar eclipse in the United States on August 21, 2017. Today, April 8, 2024, another total solar eclipse can be seen in the United States. The shadow width caused by today's solar eclipse on the earth's surface is about 115 miles wide, covering about 32 million people in the United States, which is wider than the 66 miles of the 2017 solar eclipse shadow width and 12 million more people in the United States. Observed rom the earth, the angle-span of the sun is almost the same as the angle-span of the moon. About 0.52 degrees. Since the earth's rotation angular speed is about 0.25 degrees per minute, the duration of the solar eclipse is a little bit over 2 minutes. In the 21st century, there will be 8 total solar eclipses in North America, with an average of one every 12 years. The next total solar eclipse in North America will occur 20 years later, on August 23, 2044.
