Below are a selection of news articles, of varying sensationalism, to remind everyone what crowded and potentially dangerous solar, neighborhood that we occupy. NASA Asteroid Hunter Explains the Risks that Near Earth Objects Pose to Planet, Hanna Osborne, Newsweek, http://www.newsweek.com/asteroid-day-nasa-risk-earth-neos-629965 Space rock found to be travelling With Earth Scientists have discovered that Earth is being tailed by an Asteroid, Sean Martin, Express. http://www.express.co.uk/news/science/868068/ASTEROID-belt-nasa-end-of-the-world-earth-orbit Asteroid 2012 TC4: Space rock could come back and Smash into Earth in the near future The asteroid which had a near miss with Earth could come back and smash into the planet in the future, researchers have warned, Sean Martin, Express, Oct 13, 2017 http://www.express.co.uk/news/science/866149/Asteroid-2012-TC4-hit-Earth-end-of-the-world-nasa-esa How We Discovered, Lost, and Rediscovered the First Asteroid. It was a lot of math and staring through telescopes. Popular Mechanics http://www.popularmechanics.com/space/solar-system/a28667/how-we-discovered-lost-and-rediscovered-the-first-asteroid/ Samples Brought Back From Asteroid Itokawa Reveal 'Rubble Pile' Had a Violent Past, Curtin University Posted October 18, 2017 http://spaceref.com/asteroids/samples-brought-back-from-asteroid-itokawa-reveal-rubble-pile-had-a-violent-past.html Near-Earth Objects News https://watchers.news/category/near-earth-objects/ What I am worried about is not the asteroids that we know about. What worries me are the asteroids that we do not know about and appear abruptly out of the darkness like a drunk driver on a New Orleans street. Go read “Asteroid 2017 TF5 flew past Earth at 0.73 LD, 4 days before discovery, October 16, 2017 https://watchers.news/2017/10/16/asteroid-2017-tf5/ Unlike the dinosaurs, we have, if we want it, the technology to possibly defend ourselves from wayward asteroids.
