On April 13, 2029, a 370-meter wide asteroid formally known as 99942 Apophis will pass by Earth at a distance of about 19,000 miles. While 19,000 miles sounds like a long way away, in astronomical terms it’s actually the equivalent of having a bullet whiz by your ear. There are man-made satellites that orbit farther from Earth. Even scarier, it was initially believed there was a slight chance Apophis could strike the Earth in 2036. That’s why, when the asteroid and its trajectory was discovered in 2004, scientists named it after the Egyptian god of chaos who, by the way, is also the villain in the TV series, Stargate-SG1.
On Friday, July 27, the full moon will pass through the shadow of the Earth. The blood moon will last for 103 minutes, the longest “blood moon” lunar eclipse of the century, lasting 26 minutes longer than the last total lunar eclipse, in January. Although most of the world will be able to see the blood moon, most of North America will not.
