As people are traveling to see the 2017 solar eclipse, here are some fun facts about the big event that is about to happen. It’s never too late for knowledge, right?
1. This will be the first total solar eclipse in the continental U.S. in 38 years. The last one occurred February 26, 1979. Unfortunately, not many people saw it because it clipped just five states in the Northwest and the weather for the most part was bleak. Before that one, you have to go back to March 7, 1970.
2. A solar eclipse is a lineup of the Sun, the Moon, and Earth. The Moon, directly between the Sun and Earth, casts a shadow on our planet. If you’re in the dark part of that shadow (the umbra), you’ll see a total eclipse. If you’re in the light part (the penumbra), you’ll see a partial eclipse.
3. Everyone in the continental U.S. will see at least a partial eclipse. In fact, if you have clear skies on eclipse day, the Moon will cover at least 48 percent of the Sun’s surface. And that’s from the northern tip of Maine.
4. The center line crosses through 10 states. After a great west-to-east path across Oregon, the center line takes roughly nine minutes to cross a wide swath of Idaho, entering the western part of the state just before 11:25 a.m. MDT and leaving just before 11:37 a.m. MDT. Next up is Wyoming, where the umbral center line dwells until just past 11:49 a.m. MDT. The center line hits the very northeastern part of Kansas at 1:04 p.m. CDT and enters Missouri a scant two minutes later. At 1:19, the shadow’s midpoint crosses the Mississippi River, which at that location is the state border with Illinois. The center line leaves Illinois at its Ohio River border with Kentucky just past 1:24 p.m. CDT. Totality for that state starts there two minutes earlier and lasts until nearly 1:29 p.m. CDT. The center line crosses the border into Tennessee around 1:26 p.m. CDT. Then, just past the midpoint of that state, the time zone changes to Eastern. The very northeastern tip of Georgia encounters the center line from just past 2:35 p.m. EDT until not quite 2:39 p.m. EDT. Finally, it’s South Carolina’s turn. The last of the states the center line crosses sees its duration from 2:36 p.m. EDT to 2:39 p.m. EDT. One further note: The extreme northeast part of Georgia does experience some totality, but at no point does the center line pass through that state.
5. Totality lasts a maximum of 2 minutes and 40.2 seconds. That’s it. To experience that length, you’ll need to be slightly south of Carbondale, Illinois, in Giant City State Park.
This eclipse will be the most-viewed ever due to media attention, superb coverage of the highway system in our country, and the vast number of people who will have access to it from nearby large cities. Remember to always wear the proper eye protection for eclipse viewing. Enjoy this phenomenal event!
