How many pixels would make up our solar system on this image of the center of the Heart Nebula?
Answer: only 0.014 pixel !
Neptune's orbit is 499 light minutes in diameter. The camera has an image area of 4000 x 4000 pixels. The Heart Nebula's width, 200 light years, makes up approximately 3000 pixels across the original image, of which the image above is only a detail. One light year is then 15 pixels, so 499 light minutes is 0.014 pixel.
