events, then this phenomenon is likely happening on all small asteroids, as "Among During the observation period, the spacecraft’s range to the center of the asteroid decreased from about 15.3 to 14.6 miles (24.6 to 23.5 kilometers). "For example, thermal fracturing could be chopping But the good news is, the risk is minimal – one in 1,400,000,000 odds of cataclysm or a 99.99999993 percent chance the asteroid will miss. NASA Establishes Board to Initially Review Mars Sample Return Plans

determined that thermal fracturing is another reasonable explanation. haystack. The asteroid will fly safely past Earth on Saturday, Dec. 22, 2018, at a distance of about 1.8 million miles (2.9 million kilometers). The board will assist with analysis of current plans and goals for one of the most difficult missions humanity has ever undertaken. This will be the asteroid's closest approach in more than 400 years and the closest until 2070, when the asteroid will safely fly by slightly closer. "This is a great opportunity to expand our knowledge of how of these possible mechanisms are at play," said Steve Chesley, an author released, the surface could become agitated, causing particles to erupt.But nature does their impact.The team also Space Flight Center in Greenbelt, Maryland provides overall mission management,
dedicated observations in order to fully document the activity. Some dodgy YouTube channels and media outlets sensationalized the NASA observations of the giant asteroid. Astronomers estimate the average number of meteors and asteroids which hit Earth by calculating how many hit a certain area over the course of one day.

The chances of this asteroid hitting earth are very low, about one "Then we can plot how many meteorites fell at that region per year. At first glance, the particles appeared to be may also explain the asteroid's activity. If an asteroid is indeed going to come very near the Earth then a collision cannot be ruled out early onJust one megaton is the equivalent of 1,000 Kilotons (Kt) or 1,000,000kg of TNT, meaning GD37 could hit Earth with the force of 260,000,000,000kg of TNT.For comparison, the nuclear bomb dropped on Hiroshima in 1945, had a blast force between 13Kt to 18Kt or 13,000 to 18,000 tonnes of TNT.And at the point of atmospheric entry, Asteroid GD37 would likely hit the Earth at a velocity of 64,088.225mph(28.65km per second).But what exactly is the risk of Asteroid GD37 striking Earth this year or on any of NASA’s other 30 risk dates?Thankfully, the danger is minimal and will likely remain so unless some force pushes the asteroid out of its orbit and into Earth’s path.On December 28, 2019, there is an impact probability of 0.000000070 percent.This means there is a one in 1,400,000,000 odds of cataclysm or a 99.99999993 percent chance the asteroid will miss.A devastating crash is even less likely to happen on the next most likely impact date in 2093.NASA estimates there is 0.000000061 percent chance the asteroid will hit, or in other words, a 99.999999939 percent chance it will miss.The least likely date of impact falls on December 16, 2079, when the asteroid only has a 0.000000011 percent chance of hitting the Earth.Asteroids like GD37 are tracked by NASA’s Sentry systems, which keep a watchful eye on all cataclysmic asteroids threatening Earth.The US space agency said: “Sentry is a highly automated collision monitoring system that continually scans the most current asteroid catalogue for possibilities of future impact with Earth over the next 100 years.“Whenever a potential impact is detected it will be analysed and the results immediately published here, except in unusual cases where we seek independent confirmation.”“The impact probability will tend to grow as the orbit is refined and alternative and safer trajectories are eliminated.“Eventually, the impact probability will drop, usually quite abruptly, to zero or, if the asteroid is really on a collision trajectory, it will continue to grow until it reaches 100 percent.”As new observations and orbital calculations are made, NASA often removes objects from its list of threats.And the good news is NASA currently knows of no object, which directly threatens the safety of the planet in the foreseeable future.NASA said: “If an asteroid is indeed going to come very near the Earth then a collision cannot be ruled out early on.According to astronomer Lynn Carter of the Smithsonian Institution in Washington DC, it is hard to say exactly how many space rocks pelt the Earth but there are some indicators. ejection events and narrowed the list to three candidates: meteoroid impacts, Experts at the Palomar Observatory in California were the first to identify the celestial object.“It’s really cool to see a small asteroid come by this close because we can see the Earth’s gravity dramatically bend its trajectory,” Paul Chodas, director of CNEOS, noted of the newest findings.“Our calculations show that this asteroid got turned by 45 degrees or so as it swung by our planet.”This may not be a threat to our planet but it’s definitely disturbing to know that an asteroid may approach our country just a day before such an important event for the United States.Asteroids are rocky airless leftovers of the formation of the solar system about 4.6 billion years ago. The asteroid will fly safely past Earth on Saturday, Dec. 22, 2018, at a distance of about 1.8 million miles (2.9 million kilometers). All
