International Asteroid Day in 2021

Today is #WorldAsteroidDay. Asteroid Day is the anniversary of the Tunguska impact over Siberia, which occurred in 1908. Tunguska is the largest asteroid to affect the earth in modern times. To commemorate the day, Howard printed a cut that is out of this world. #AsteroidDay https://t.co/t1rNdduhHx

Happy International #AsteroidDay! One of the largest asteroid impacts on Earth was 382 million years ago, where Mt. Hancock (120 mi. north of Las Vegas) was ground zero. Learn more about this cataclysmic event, other impacts and why we celebrate today! https://t.co/Xj9x8pzZEj https://t.co/4mn9ucJI7Z

@electroboyusa Mine seems to be working just fine. Which is a perfect time to remind people that today was Asteroid Day. Our hopes were set hi but sadly our target remains at large. For now. https://t.co/hJ3CoEdb9V

When extinction is possible, it's worth reducing even very small risks to zero, if we possibly can. That's why I'm supporting Asteroid Day. https://t.co/QuOd9507fa
