Watch this video from Scott Manley, tracing thirty years of asteroid discovery and the deployment of new and more sensitive instruments to find them. From the green main belt asteroids, to the yellow dots that cross Venus’ orbit, to the red that come near our own orbit … space has a lot of stuff in it.
