  how do you know?

  years and years of experience and seeing literally thousands of them !

  Because the asteroid moves in between exposures it gets caught at slightly different locations in different filters.

  I am finding this very educational and inspiring, thank you.
  So if i'm getting this right, the astroid has been shot three times?

  Every object in SDSS pics id shot in 5 filters: red/near infra-red/UV/far infra-red/blue-green.

  so does the shot takes so long or does the astoid move so fast? (faster than stars and galaxy's ?)

  If the telescope fixes on a particular part of the sky, the galaxies and stars don't move. It's only asteroids or others 😃 that move

  ah, so if ï spot a range of dots (lined up) in different colours, I may assume it's a moving object?
