In this video, astronomer Scott Manley shows you what it would look like if you could see all the asteroids near the Earth. This is a “360 video;” if you play it on a device that supports it (like a smartphone) you can look around in all directions.
Scott produced this video, showing asteroid discovery over the last few decades. Watching this for the first time simply shocked me, and may well be one of the reasons I started researching asteroids for my lecture.
Scott is a also a huge fan of Kerbal Space Program, and has produced a boatload of helpful training videos. In this video, Scott shows the new Asteroid Day mod for KSP, including a in-game version of the B612 Foundation’s infrared asteroid-hunting Sentinel space telescope.
