This is your Astronomy Tonight podcast.

On this day, October 12th, in the year 2000, a significant event occurred that shook the astronomical community and reminded us of our vulnerability in the cosmos. The asteroid 2000 SG344 was discovered, and initial calculations suggested it had a 1 in 500 chance of colliding with Earth on September 21, 2030. Talk about a cosmic game of Russian roulette!

This near-Earth object, measuring about 30-70 meters in diameter, caused quite a stir. Imagine an asteroid the size of a football field hurtling towards our blue marble! The discovery led to a flurry of activity among astronomers, who scrambled to gather more data and refine their calculations.

But fear not, dear listeners! As more observations came in, the odds of impact were thankfully reduced to zero. It turns out 2000 SG344 will pass by Earth at a safe distance of about 0.1 astronomical units, or roughly 15 million kilometers. That's about 40 times the distance to the Moon. Phew! Crisis averted!

This event serves as a reminder of the importance of near-Earth object detection and tracking programs. It's like having a cosmic neighborhood watch, keeping an eye out for any celestial troublemakers that might be heading our way.

So the next time you look up at the night sky, remember that there's a whole team of astronomical detectives out there, working tirelessly to keep us safe from errant space rocks. It's just another day in the office for these celestial bodyguards!
