, and in 2052 it could come dangerously close to Earth. The more the asteroid was observed, the greater that risk became."
With the predicted collision risk uncomfortably high, the asteroid disappeared for several months in the glare of the sun as its orbit brought it closer to our star. Astronomers knew that by the time the space rock would reach darker skies again, it would be too far away and therefore too faint to be observed by most ground-based telescopes. They therefore solicited help from the Very Large Telescope, which, with its 26-foot-wide mirror, had a reasonable chance of detecting the rock.
The telescope managed to detect 2021 QM1 when the space rock had a magnitude of 27. For comparison, the magnitude of the sun, the brightest object in our sky, is minus 27.
