A useful summary of the search for asteroids, particularly dangerous asteroids such as 2022 AP7 which has been obscured by sunlight until quite recently.
As mentioned in the video description, the NASA Earth Impact Monitoring website is also worth a visit whenever we see a scary asteroid story in the media.
Assume a Year to be an Earth-year, one Earth orbit of the sun. So if it takes five years to complete its orbit then it travels one-fifth of its orbit during our Earth year.

He says (around 5.34) that this asteroid takes roughly five years to orbit the sun, so for every orbit of the earth, it orbits five times.
Is astronomy and the maths used harder than I think, or is that wrong? If so, then NASA need to give me a phone call and I can do the sums for them.
Sam - yes, he seems to have mixed up something there. I assume he means it orbits the sun in one fifth of a year.

djc - is that what he said? I listened to it a number of times and I'm still not sure.
