![]() Maybe someone who’s good with matter and energy can leave a comment.īut again, remember, we’re talking about speeds in the vicinity of 3,000 km / s. ![]() I’m not even sure it will leave you with solid matter, but I’m not inclined to do that math. I don’t care how massive a fragment of the Moon got ejected, instantly accelerating it to ~0.01 c is not going to leave you with one large chunk. Even if we assume there was some editing lossage and its traversal time was a half-minute longer, at 140 seconds, we get 2,488 km / s, which is about 0.83% c. That is just a hair over 1% the speed of light in a vacuum. Moving that far in 110 seconds means a speed of 3,166 kilometers per second ( km / s). This means the Big Moon Fragment (hereafter BMF) has to cover 348,283.8 kilometers. And what the heck, even though it makes no physical sense, let’s be overly generous and subtract the Moon’s 1,738.1 km equatorial radius. (Perigee is a measurement between the centers of mass of the two bodies, not their surfaces.) The Earth has an Equatorial radius of 6,378.1 km. The ejected fragment doesn’t have to traverse that entire distance, though it only has to reach the Earth’s surface. Assume Vanya accidentally zapped La Luna at its moment of perigee, which is 356,400 kilometers. How fast? Well, let’s find the slowest possible case. That ejected Moon fragment takes, according to the Netflix video player clock, just under 110 seconds to get from the Moon to the Earth. And they most certainly wouldn’t drop back and then speed up to match velocity with the parent body like some kind of magical space fairy dust.īut that arguably artistic problem aside, let’s talk about the problem of distance. Anything that “fell off” would fly in close formation with its parent body, slowly drifting further away but moving at the same velocity. There’s no atmosphere in space to cause things to fall off and slow down. You know all the coolio particle trails behind the BMF and tails behind the other impactors? Yeah, no. Here’s a link directly to the video file (MP4, no audio). The video couldn’t be loaded inline for some reason. And then, a little less than two minutes later, this. So, Vanya bleaches out, bad plans are executed, the sound of a gunshot somehow nullifies Vanya instead of charging her even further, magic energy beam somehow hits the Moon. And in order to do that, I’m going to deploy, for the first time ever, a WordPress Spoiler Cut™ on this here blog o’ mine, because this post is spoilerrific. I have to get into why the ending, the very last few minutes of season one, just didn’t work for me. I thought it was pretty good! It was a decent mix of good decisions and bad decisions by people in the story, I liked most of the characters and their portrayals, and I thought the narrative arcs came to good places. “But this one will be a record close approach by a known object of this size.”įrom the fleeting glimpses they have had, astronomers reckon 2012 DA14 is 45 metres across – similar in size to the space projectile that exploded over the uninhabited Tunguska region of Siberia in 1908, ripping up 80 million trees across 2000 square kilometres.Not long ago, Kat and I got around to watching The Umbrella Academy’s first season on Netflix. “I’m not easily surprised by close-Earth approaches any more,” says Don Yeomans, who heads NASA’s near-Earth object office in Pasadena, California. Asteroid 2012 DA14 will fly inside the ring of communications satellites in geosynchronous orbit but sail safely above the orbits of the International Space Station and the Hubble space telescope. On 15 February 2013, the errant rock will skim Earth just 25,000 kilometres above our heads – that’s 500 times nearer than the much-publicised asteroid Apophis came earlier this month, and even closer than Apophis will get on its much-hyped return in 2029. The result was sensational: asteroid 2012 DA14 was on near-collision course with the Earth. ![]() Telescopes around the world swung into action, checking the new asteroid’s orbit. He alerted the Minor Planet Center in Cambridge, Massachusetts, which collects information about asteroids and comets. Suddenly he spotted a speck of light speeding through the constellation Boötes. Last February, a young dental surgeon called Jaime Nomen was sailing along the Mediterranean coast of Spain, checking images on his laptop from an observatory 600 kilometres away. IT COULD easily be the plot for a Hollywood disaster movie.
