But before this impending doom, a few words about Trump, et al.
- With much showmanship, Donald Trump this morning talked to Vladimir Putin on the phone. This was a well-orchestrated affair, as American school teacher Marc Fogel was released from Russia, and met with Trump yesterday, showing good faith by his pal Vlad. This was a prisoner swap with Alexander Vinnik, a convicted Russian criminal. Initial step in ending the war in Ukraine. By what has so far been leaked, the war will soon end, with Ukraine losing a lot of territory and being banned from joining NATO.
- The U.S. Senate today confirmed 43-year old Tulsi Gabbard as Director of national intelligence. She represented Hawaii as a Democrat in the U.S. House from 2013 to 2021. Only Republic to not vote for Gabbard was Senator Mitch McConnell, who couldn't care less what Trump will do to him. I posted on everything you should know about Tulsi on 30December2024. She plays the ukulele. By the time you read this, Robert F. Kennedy Jr. should get a unanimous Republican vote to become the next Secretary of Health and Human Services.
Late in January NOAA indicated that an asteroid the width of an NFL football field will approach Earth in less than a decade with a 1% chance of actually hitting our planet.
- A week later, the asteroid had a name, 2024 YR4, but was not as large, perhaps 130 feet wide, to swing past Earth on 22December2032, but now with a 1.9% chance of striking us.
- Then on February 7, latest calculations increased the percentage to around 2.3%.
- The odds of an average golfer making a hole in one are 12,000 to 1, or only 0.01%. I've never gotten one. At this probability, I wouldn't worry about this asteroid.
- The odds of a 20-handicap golfer, which is about where I am, getting a birdie (one under par) are one in every 60 holes. This means I will only get a birdie once in three rounds. But a 1.7% chance of my getting a birdie on my next hole is actually very hopeful. Only a couple of years ago I got three birdies over four holes, and putted just off the green to miss the fourth. So 1.7% can happen, again and again, much too often.
- Asteroid 2024 YR4 has a 2.3% chance of striking our planet. That is kind of scary, because I get close to getting a birdie too often.

- 2.3% of hitting Earth.
- It is now 196 feet wide.
- An asteroid is chunk of rock, circulating in the solar system since its creation.
- When first sighted, on Christmas Day, it was 500,000 miles from us, and moving AWAY.
- That is twice the distance of the Moon.
- But its orbit will result in this asteroid heading back our way.
- If it hits us, it will be on 22December2032.
- An asteroid of this size impacts Earth every few thousand years.
- In 1908, a 98 foot-wide asteroid struck the Podkamennaya Tunguska River in a remote Siberian forest of Russia and destroyed 830 square miles of forest.
- In 2013, a 66 foot-wide asteroid struck Chelyabinsk, Russia, exploding in the air, releasing 20 to 30 times more energy than the first atomic bomb, generating brightness greater than the sun, damaging more than 7000 buildings and injuring more than a thousand people.
- Asteroid 2024 Y4 has 8 times the mass of the 1908 asteroid and 26 times that of the 2013 asteroid.
- Like the 2013 asteroid, 2024 YR4 is expected to blow up in our atmosphere and not create a crater.
- This explosion would equal around 8 megatons (8,000 kilotons, kt) of TNT, the equivalent of 500 Hiroshima atomic bombs.
How does this new asteroid compare with the Chicxulub impactor that killed off the dinosaurs 66 million years ago?
- The Chicxulub asteroid was at least 6 miles in diameter, which is 162 times larger than 2024 YR4.
- The mass of the dinosaur-killer was around 4 million times greater than our current worry.
- The Chicxlub crater in the Yucatán Peninsular is 120 miles in diameter.
- We won't closely see asteroid 2024 YR4 again until 2028. This is awfully close to 2032. How much time do we need to internationally make a decision to fund and construct a fail safe option to divert this asteroid?
- NASA's 2022 DART mission successfully nudged an asteroid off course using a spacecraft, a strategy known as a kinetic impactor.
- Lasers could vaporize part of the asteroid, creating a thrust effect, pushing it off course.
- A gravity tractor in the form of a large spacecraft could slowly tug the asteroid away using its own gravitational pull.
- Watch this video of NASA sending a nuclear warhead to strike the asteroid.
- There is a 90% chance that if this incoming asteroid hits Earth, it will explode in the ocean or over uninhabited land.
In short, no need to panic at this time, although clearly, we need to reach an international agreement pretty soon to be ready for a possible worst case scenario. Be aware of this Torino scale.

At this time, it seems like Asteroid 2024 YR4 will only affect this area of Earth.
