>The spacecraft is 18,675,137.9 km (11,604,190 miles) away from
comet Tempel 1
That is a remarkable level of accuracy,
0.1 km in over 18 million kilometres,
ie 1 part in 180 million. Amazing!
I wish I could park my car to that degree of accuracy. If I am
entering a parking bay 2.5 metres wide, 1/180, millionth of that width
would be 0.0001 millimetres.
Come on NASA, use realistic numbers. That picture was taken from 19
million kilometres - that is the appropriate level of precision.
