thai astronomer says dont worry about big asteroid

A specialist with the National Astronomical Research Institute of Thailand has sought to calm fears that Asteroid 2006 QQ23, which is double the height of Baiyoke II Tower in Bangkok, would hit Planet Earth on Saturday.

Sitthiporn Duantakhu, an official of the NARIT (National Astronomical Research Institute of Thailand), said although the National Aeronautics and Space Administration (NASA) is watching the QQ23 asteroid, it doesn’t mean it would crash into the earth and turn Saturday into doomsday as rumoured among Thai Facebook users.

It may be useful and interesting to have some knowledge of asteroids and comets that have collided with Earth. The Younger Dryas impact of about 12,000 years ago might be of particular interest. Here is a bit more information about QQ23.

"NASA has detected a potentially hazardous asteroid that has a chance of hitting Earth next month. According to the space agency, the massive asteroid is dangerous because its orbit intersects with that of Earth.

The asteroid, known as 2006 QQ23, was first observed on Aug. 21, 2006. Based on the data collected by NASA’s Center for Near Earth Object Studies (CNEOS), the asteroid is traveling at a speed of 10,400 miles per hour.

It has an estimated diameter of 1,870 feet, making it significantly taller that most notable skyscrapers around the world such as the Empire State Building, the Taipei 101 and the Petronas Twin Towers.

According to CNEOS, the asteroid has been frequently approaching Earth and Venus since 1901. For this year’s approach, 2006 QQ23 is expected to zip past Earth on Aug. 10 at 7:23 am ST. It is expected to fly past Earth from a distance of 0.04877 astronomical units or around 4.6 million miles away.

Although it seems 2006 QQ23 will be traveling at a safe distance from Earth, NASA still classifies it as a potentially hazardous asteroid, which means it still has a good chance of hitting the planet due to its trajectory.

According to NASA, 2006 QQ23 is an Atens asteroid. Unlike other asteroid classifications, Atens objects are those that orbit around the Sun and crosses Earth’s path at two points.

These intersections points could cause the direct collision between Earth and 2006 QQ23. Given the size of the asteroid, a direct hit could certainly wipe out large cities or even an entire country during the initial impact. To put it into perspective, the meteor that caused the Tunguska event in Russia in 1908 was about 620 feet long, making it around three times smaller than 2006 QQ23.

When the meteor exploded mid-air, it released an energy 1,000 times greater than the atomic bomb used by the U.S. in World War 2. The explosion was so strong that it leveled 830 square miles of forest, an area that’s almost as big as Jacksonville, Florida."

What time GMT is 07.23am ST?

I take from this article that QQ23 approaches Earth approximately every 13 years and that it has been observed doing this at least since 1901. It is more than a curious event. If it should collide with Earth it would very likely be a tragic event for Earth's population and may be measured in comparison to an unknown number of hydrogen bombs exploding at one location. What might be the expected consequences? As most of Earth's surface are oceans what might be the results? The first thought is that a large tsunami would be created that might have a devastating effect on many coastal fronts. Would it penetrate to the Earth's mantle and possibly disturb the delicate balance among the various tectonic plates to the point that earthquakes and volcanoes are produced? And if it hit a continent?

Do the observations of the passes reveal that it's orbit always takes further or closer to Earth? Does it pass on either side randomly with varying distances. The point being is that there may be a significant chance of a collision during one or other of it's near passes.

I seem to remember that one missile had hit an asteroid and another recently landed on an asteroid which demonstrates a present technology capable of redirecting an asteroid's orbit. IMO nations must take the responsibility of providing the means for redirecting this or other threatening asteroids from orbits that threaten our Earth.

Would it be of interest to note the occasional city-killing asteroid passing near Earth, such as the following:

26 July "A 427-foot-wide asteroid whizzed within 45,000 miles of Earth yesterday. Although 2019 OK was wider than the #StatueofLiberty is tall, it's relatively small compared to the 6-mile-wide rock that hit modern-day Mexico and wiped out the dinosaurs 66 million years ago. @NASA NASA tracks about 90% of those types of big asteroids." :shock:
