For those who do not know, B612 Foundation is an organization founded in 2002 by former astronauts and scientists who dedicated their lives to protecting Earth from the apocalypse.
The B612 Foundation is made up of former astronauts and scientists who focus on defending Earth from the Apocalypse.
2005 Nasa 90% of the discovered asteroids with a diameter of at least 140 m are not an immediate threat.
But millions of asteroids in the range of 15 to 140 m are "near the earth"
And there are worldwide An estimated 18,000 are prosecuted and the majority is not even monitored, reports News.com.au.
Lasers and nuclear weapons could theoretically be used to destroy an incoming asteroid, but experts believe that we would not even know about the asteroids unti
B612 Foundation President Danica Remy said that surgical telescopes have only a small number of Can absorb asteroids.
"The field of view of the telescopes is very small and the sky is very large," said Remy
"We can currently determine in advance if any of the 18,000 asteroids we've observed will hit us, but we would Just to know if any of the several millions that we have not observed on a train to Earth is a land-based telescope watching it.
"It could be selected, but it is more likely that it is not true and that we have it
An asteroid, larger than the Eiffel Tower, flew over The Earth earlier this month.
Ms. Remy told News.com.au she must track all near-Earth asteroids and the rate of Raise "Discovery" before it's too late.
She added, "It's 100 percent safe. We're hit, but we're not one hundred percent sure when.
"At the moment we are slowly making our discoveries: The world discovers about 1000 asteroids per year and we want to accelerate that detection rate to 100,000 per year, but have no space instruments or telescopes to do that," she said.
"We must find them before they find us."
Previously, the space agency admitted that there are numerous deadly asteroids that have not yet been discovered.
Congress hired the agency to detect 90% of all NEOs When NASA admitted that only a third of such objects were being tracked.
The B612 Foundation has pushed for more global funding.
Ms. Remy added, "The important thing is that we need a comprehensive map that shows the location, characteristics and routes to all these asteroids so we can defend ourselves.
" Asteroids do not care where they meet. It could be Australia, Japan or Columbus Ohio
"It's really a global problem."
What Wikki says about the B612 Foundation:
The B612 Foundation is a private nonprofit foundation headquartered in Mill Valley, California, United States dedicated to planetary defense against asteroids and other near-earth objects (NEO). It is primarily led by scientists, former astronauts and engineers from the Institute for Advanced Study, the Southwest Research Institute, Stanford University, NASA and the space industry.
As a non-governmental organization, it has conducted two research lines to help discover NEOs that might one day hit the Earth, and to find the technological means to redirect their way to avoid such collisions. The organization has released the true rate of "City Killer" effects on the same scale as the explosive 1904 Tunguska event, a rate three to ten times greater than previously thought, or about every century on average. It also supported the Association of Space Explorers in establishing the United Nations for the International Asteroid Warning Network and an advisory group on asteroid mission planning.
In 2012, the Foundation announced that it would design and build a privately funded observatory for asteroid finds, the Sentinel Space Telescope, which will be launched in 2017-2018. Once stationed in a heliocentric orbit around the Sun, similar to Venus, Sentinel's super cooled infrared detector will help identify dangerous asteroids and other NEOs at risk of colliding with Earth. In the absence of substantial planetary defense offered by governments worldwide, B612 is conducting a fundraising campaign to cover the Sentinel mission, which is estimated to be $ 450 million for 10 years of operation. Fundraising was very slow – only $ 3 million was collected in 2012 and 2013 – and as of June 2015, NASA re-examines its dependency on the private sector approach to space-based investigations. 
The B612 Foundation is named for the asteroid home of the eponymous hero of Antoine de Saint-Exupéry's The Little Prince.
In April 2018, the B612 Foundation reported: "It is 100 percent certain that we will be hit (by a devastating asteroid), but we" it is not 100 percent sure when. "

Our expanded team of employees, employees and partners are the best and unparalleled in their expertise. The success of our work depends on it.
We believe that it is our responsibility to use our knowledge and expertise to work for the betterment of humanity.
We are driven by a thirst for knowledge. Our commitment to discovery is fueled by a sense of wonder for the universe and our evolving ability to explore it.
We believe that we are meeting unmet challenges. We do not believe in the best, but to research and develop solutions with the best results.
Whether you are a student, citizen scientist or C-level executive, we need your help to support the cause and spread the word.
Our Asteroid Institute is a B612 program that works with major institutions around the world working on asteroid projects, including research, science and technology. Our leadership drives strategy and operations, and the board oversees our long-term vision. Our founding circle, the asteroid circle and the global donor community make our work possible.
Here is an excerpt from Wikipedia on the last major extinction event of an asteroid:
The Cretaceous-Paleogene (K-Pg) extinction event, also known as the Cretaceous-Tertiary (KT) extinction, was a sudden mass extinction of about three quarters of plant and animal species on Earth, about 66 million years ago. Except for some ectothermal species such as leatherback turtles and crocodiles, no tetrapods weighing more than 25 kilograms survived. It marked the end of the Cretaceous and thus the entire Mesozoic and opened the Cenozoic, which continues to this day.
In the geological record, the K-Pg event is characterized by a thin layer of sediment known as K-Pg. Pg limit, which can be found all over the world in marine and terrestrial rocks. The Border Tone shows high levels of metal iridium, which is rare in the earth's crust but abundant in asteroids.
As originally proposed in 1980 by a team of scientists led by Luis Alvarez and Walter Alvarez, it is now generally thought that the K-Pg extinction by the impact of a 10 to 15 km wide comet or asteroid 66 million years ago which destroyed the global environment, mainly due to a prolonged winter impact that prevented photosynthesis of plants and plankton. The impact hypothesis, also known as the Alvarez hypothesis, was supported by the discovery of the 180-kilometer-wide Chicxulub crater in the Gulf of Mexico in the early 1990s, which provided conclusive evidence for the K-Pg boundary clay represented by debris asteroid impact. The fact that the extinction occurred simultaneously provides strong evidence that they were caused by the asteroid. A 2016 drill project in the Chicxulub summit ring confirmed that within a few minutes, the gypsum ring consisted of granite that had been deeply ejected into the ground and contained little gypsum, the usual sulphate-rich seabed rocks in the region: it would have vaporized and scattered an aerosol into the atmosphere, the longer-term impact on the climate and the food chain.
