The asteroid Lin Yun chose was not far from the moon, with a distance of only several hundred thousand kilometers, close to the distance between the earth and the moon. In fact, there were many asteroids within this range, but this asteroid was the largest.
According to Lin Yun's rough calculation, the diameter of this small asteroid was about thirty to forty kilometers, which was quite large by asteroidal standards. The vast majority of noticeable asteroids had diameters of less than a kilometer, and many were only several tens of meters.
The volume of an asteroid with a diameter of one kilometer is tens of thousands of times smaller than that of an asteroid with a diameter of thirty to forty kilometers.
On the journey to that asteroid, Lin Yun let Star One stop at some smaller asteroids along the way.
Every time they would stop, Lin Yun would deploy a detector. In an instant, he could detect some of the resources within those asteroids.
