Summary of These are the asteroids to worry about

00:00:00 - 00:20:00

The video explains how asteroids are detected and why they are dangerous. It also mentions that there is no known way to prevent an asteroid from hitting Earth, but that efforts to reduce the chance of a global extinction event happening in our lifetimes are ongoing.

• 00:00:00 asteroid detection is difficult for several reasons, including the fact that most asteroids are not very big. This video explains how one way to detect asteroids is by looking for moving objects that are orbiting around the sun.
• 00:05:00 An asteroid is a small, rocky object in space. These objects can be dangerous if they hit the Earth, and it is important to keep an eye on them because even once you've detected them, it's difficult to predict their future movements.
• 00:10:00 The asteroid that killed the dinosaurs 65 million years ago was 10 kilometers in size, and smaller asteroids can still cause significant damage. There is no way to prevent an asteroid from hitting Earth, but work done so far has reduced the chance of a global extinction event happening in our lifetimes.
• 00:15:00 asteroid impacts are a real threat, but there is no known way to deflect them, and even attempts at evacuation may not work. However, KiwiCo offers subscriptions for kids that help them learn and have fun, and their products come with all the supplies needed.
• 00:20:00 The asteroids mentioned in this video are those that are most likely to hit Earth, and should be taken seriously.
