Car-sized asteroid is spotted just HOURS before narrowly skimming past Earth's satellites at 24,000 miles from the planet's surface



  • The 2018 BD asteroid is 8.2 to 18 feet (2.5 to 5.5 metres) wide
  • This is third time an asteroid has flown past under one lunar distance this year
  • Its next close approach will be on 19th November 2018
  • It won't be coming as close as yesterday's approach for another 115 years
A newly-discovered asteroid hurtled past our planet at a distance of just 24,168 miles (38 895km) yesterday - just seven hours after it was discovered. 
The car-sized 2018 BD asteroid is 8.2 to 18 feet (2.5 to 5.5 metres) wide and passed so close to our planet it was nearly at the altitude at which satellites orbit.
Anything that flies closer than six million miles of our planet is a near earth asteroid and could cause severe damage were it ever to crash into Earth.

The asteroid was discovered at 08:24 UTC (08:24 GMT, 03:24 ET) on 18th January by Catalina Sky Survey and flew by at 15:43 UTC (15:43 GMT, 10:45 ET) that day. 
This is the third time an asteroid has flown past our Earth within one lunar distance since the start of this year, 
Its next close approach will be on 20:37 UTC (20:37 GMT, 15:37 ET) on 19th November 2018 - but it won't be coming as close as it was yesterday for another 115 years at least.
The news comes just days after it was revealed asteroid 2019 BC, which is larger than the Burj Khalifa, is due to fly past our planet in less than two weeks.

THE 2018 BD ASTEROID

A newly discovered asteroid hurtled past our planet at a distance of just 24,168 miles (38 895km) yesterday (18th January) - just seven hours after it was discovered. 
The 2018 BD asteroid is 8.2 to 18 feet (2.5 to 5.5 metres) wide and passed so close to our planet it was nearly at the altitude at which satellites orbit.
Anything that flies closer than six million miles of our planet is a near earth asteroid and could cause severe damage were it ever to crash into Earth. 
The asteroid was discovered at 08:24 UTC on 18th January by Catalina Sky Survey.
This is the third time an asteroid has flown past our Earth within one lunar distance since the start of this year, writes Watchers.
It's next close approach will be on 20:37 UTC on 19th November 2018 - but it won't be coming as close as it was yesterday for another 115 years at least.The 2002 AJ129 asteroid has been classed a 'potentially hazardous' by Nasa and will fly past at speeds of 67,000mph (107,826kmh).
This makes it nearly 15 times faster than the world's quickest manned aircraft - the hypersonic North American X-15, which travelled at 4,520mph (7,300kmh).   
The asteroid is around 0.7 miles (1.1km) wide - making it longer than the Burj Khalifa in Dubai, which stands at 0.5 miles high (0.8km).
It is set to pass by our planet on the 4th February at a distance of around 2,615,128 miles (4,208,641km) away - which is relatively close in space terms.
The asteroid was discovered at 08:24 UTC on 18th January. This is the third time an asteroid has flown past our Earth within one lunar distance since the start of this year

PLANETARY DEFENCE

Anything that flies closer than six million miles of our planet is a near earth asteroid and could cause severe damage were it ever to crash into Earth.
Deflecting an asteroid that is on an impact course with Earth requires changing the velocity of the object by less than an inch per second years in advance of the predicted impact.
Nasa is currently moving forward with a refrigerator-sized spacecraft capable of preventing asteroids from colliding with Earth. A test with a small, nonthreatening asteroid is planned for 2024.
This is the first-ever mission to demonstrate an asteroid deflection technique for planetary defence.
The Double Asteroid Redirection Test (DART) would use what is known as a kinetic impactor technique—striking the asteroid to shift its orbit. For reference, the distance between the Earth and the moon is 238,855 miles (384,400 km). 
Nasa describes asteroids as 'hazardous' if they come within 4,600,000 miles (7,403,00km) of our planet.  
Currently Nasa would not be able to deflect an asteroid if it were heading for Earth but it could mitigate the impact and take measures that would protect lives and property.
This would include evacuating the impact area and moving key infrastructure.
Finding out about the orbit trajectory, size, shape, mass, composition and rotational dynamics would help experts determine the severity of a potential impact.
However, the key to mitigating damage is to find any potential threat as early as possible.
'As of December 24, there are 17,495 known Near-Earth Objects (NEOs) around our planet; 17,389 are asteroids', a Nasa spokesperson told the Express last month.
'This year, we discovered 1,985 new near Earth asteroids. There were 1888 such objects discovered in 2016 and 1,571 in 2015'.The news comes just days after it was revealed asteroid 2019 BC, which is larger than the Burj Khalifa, is due to fly past our planet in less than two weeks. The asteroid is around 0.7 miles (1.1km) wide - making it longer than the Burj Khalifa in Dubai (pictured)

The Double Asteroid Redirection Test (DART) would use what is known as a kinetic impactor technique—striking the asteroid to shift its orbit.
The impact would change the speed of a threatening asteroid by a small fraction of its total velocity, but by doing so well before the predicted impact, this small nudge will add up over time to a big shift of the asteroid's path away from Earth.
In February 2013 a 19-metre meter (62-feet) meteor exploded in the skies above Chelyabinsk in Russia.
The energy - which was equivalent to 500,000 tonnes of TNT - and injured more than 1,000 people.

Design and Construction of Flying Aircraft Carriers with SWARMS of ‘Gremlin' drones My (BWB) blended wing body circular design will make it look like a flying saucer with hull and wing thickness of 25 inches or more making it indestructible in heavy seas, unlike the Russian design.  A pro totype was even tested in the 1950's, but today with computers and light materials of construction  we can build huge air ships more than 600' in diameter. Project 1794 is from the early 50's, by the United States Air Force and AVRO Aircraft. It used to be secret, but in 2012 the information has been declassified. I was really hyped when I found these two reports online at the National Archives, placed a link on my IFO site so that others could find it, but it didn't really get picked up. Kind of understand why: on the National Archives these pictures are not that easy to view, and they didn't color correct the scans. The video I made here is ...

KOREAN WAR 1950-1953: INTO THE FIRE

  KOREAN WAR 1950-1953   ( AP) The war that began in Korea 60 years ago, on June 25, 1950, a ghastly conflict that killed millions and left the peninsula in ruins, became “The Forgotten War” in many American minds. To a shrinking corps of aging men, however, the soldiers of Korea 1950-53, it can never be forgotten. It damaged many physically, scarred many mentally, and left men questioning their commanders’ and their nation’s wisdom. They fought many enemies – not just the North Koreans and Chinese, but also the heat, the killing cold and the cursed hills, the thirst, hunger and filth, the incompetence and hubris of their own army, and the indifference of an American homeland still fixed on the “good” war, World War II, that had ended five years earlier. In a wartime arc of desperation, triumph, retreat and final stalemate in Korea, no U.S. division sacrificed as much as the 2nd Infantry Division, losing more than 7,000 killed, one-fifth of total 36,516 U.S. dead...
