Chelyabinsk, Russia-sized Asteroid narrowly misses planet

Chelyabinsk meteorite - Wikipedia, the free encyclopedia
"The asteroid had an approximate size of 18 metres (59 ft) and a mass of about 9,100 tonnes (10,000 short tons) before it entered the denser parts of Earth's atmosphere and started to ablate.

The bulk of the object's energy was absorbed by the atmosphere, with a total kinetic energy before atmospheric impact equivalent to approximately 500 kilotons of TNT (about 1.8 PJ), 20–30 times more energy than was released from the atomic bomb detonated at Hiroshima."

As is often the case, we only detect these small ones after they whiz by.

1972 Great Daylight Fireball - Wikipedia, the free encyclopedia

The 1972 Great Daylight Fireball (or US19720810) was an Earth-grazing fireball that passed within 57 kilometres (35 mi) of Earth's surface at 20:29 UTC on August 10, 1972. It entered Earth's atmosphere at a speed of 15 kilometres per second[2] in daylight over Utah, United States (14:30 local time) and passed northwards leaving the atmosphere over Alberta, Canada. It was seen by many people and recorded on film and by space-borne sensors.[3] An eyewitness to the event, located in Missoula, Montana, saw the object pass directly overhead and heard a double sonic boom. The smoke trail lingered in the atmosphere for a number of minutes.

The atmospheric pass modified the object's mass and orbit around the Sun but it is allegedly still in anEarth-crossing orbit and passed close to Earth again in August 1997.[3] However, IAU's website states that these "suggestions have not been substantiated".[4]

There are some indications that there was at least one tsunami in New Zealand caused by an impact.

But yet some people think we shouldn't spend the money on building a defense for this.

Crazy.

Crazy.

Why should we, when we have Bruce Willis?

NASA Creates New Office to Protect Us from Asteroid and Comet Impact...

NASA Creates New Office to Protect Us from Asteroid and Comet Impact
January 11th, 2016 - NASA is taking the potential threat posed by near earth objects (NEO’s), such as asteroids and comets, more seriously than ever and has established the new Planetary Defense Coordination Office (PDCO).

The space agency says the new office will oversee all of its efforts in finding and characterizing all celestial objects that travel close to Earth as they orbit the sun. It will also coordinate any actions within and outside of NASA that may be needed to respond to potential threats of impact. “Asteroid detection, tracking and defense of our planet is something that NASA, its interagency partners, and the global community take very seriously,” said John Grunsfeld, associate administrator for NASA’s Science Mission Directorate in a NASA press release.

A meteorite contrail is seen over a village of Bolshoe Sidelnikovo 50 km of Chelyabinsk on Friday, Feb. 15, 2013​

Grunsfeld went on to say that while there aren’t any impact threats right now, events such as the huge meteor that exploded over Chelyabinsk in 2013 along with the recent close approach of the ‘Halloween Asteroid’ serve as reminders of why it’s important close approach remind us of why we need stay on guard and ‘keep our eyes to the sky’. Scientists say that the space object that exploded over Chelyabinsk, Russia in 2013 was about 17 meters across and had a mass of roughly 10,000 tons. It was reported that the blast shattered windows in about 7,000 buildings in the area and injured around 1,700 people, mostly due to flying shards of glass.

With projects such as its Near-Earth Object Program, NASA has already been involved with finding and tracking NEO’s and has been a part of international efforts to develop methods to protect Earth from significant threats of impacts. The space agency says that the new Planetary Defense Coordination Office will improve and ramp up those efforts by working with other U.S. government agencies such as the Department of Homeland Security’s Federal Emergency Management Agency as well as similar agencies from other countries. Near earth objects are found by astronomers who use a worldwide network of ground-based telescopes as well NASA’s space-based NEOWISE infrared telescope.

The Panoramic Survey Telescope & Rapid Response System (Pan-STARRS) 1 telescope in Hawaii has produced the most near-Earth object discoveries of the NASA-funded NEO surveys in 2015.​

Once an object is detected NASA says that its Center for NEO Studies at the Jet Propulsion Laboratory then will precisely predict its orbit and then will monitor its movements. NASA says since more than 90 percent of near earth objects larger than 1 kilometer have already been discovered, the space agency will focus on finding objects that are about 140 meters – about the size of an American football field – or larger. So far, astronomers have discovered more than 13,500 near-Earth objects, which vary in size from small boulders to those that are hundreds of kilometers in diameter. NASA says that about 1,500 near earth objects are spotted every year.

Great news. Would like to see this office and the space command in our military work together to protect our planet from a real threat!

Yes, they piss money away on the fiction of globull warming which can't harm us, and they ignore these which absolutely can. Fucking morons.




And the long video..
