“Imagine we could accelerate continuously at 1 g — what we're comfortable with on good old terra firma — to the midpoint of our voyage, and decelerate continuously at 1 g until we arrive at our destination. It would take a day to get to Mars, a week and a half to Pluto, a year to the Oort Cloud, and a few years to the nearest stars.”

—  Carl Sagan , book Pale Blue Dot

“What delighted me was that it's 30 years from now — not next week or next year. … That would be totally hopeless; that would be terrifying, in fact. Time is on our side in this one — that's why it's such a wonderful illustration of the process… I say 30 years is a good long time to do something about it if it is a problem … We should be thankful we have this kind of notice.”

Brian G. Marsden (1937–2010) British astronomer

On initial reports that Asteroid 1997 XF<sub>11</sub> could be on a trajectory to hit the Earth in 2028; as quoted in "Man in the News; A Cheery Herald of Fear: Brian Geoffrey Marsden" in The New York Times (13 March 1998) http://query.nytimes.com/gst/fullpage.html?res=9401E2D91F30F930A25750C0A96E958260&sec=&spon=&pagewanted=all.

“From a score of well-observed original orbits it is shown that the "new" long-period comets generally come from regions between about 50000 and 150000 A. U. distance. The sun must be surrounded by a general cloud of comets with a radius of this order, containing about 1011 comets of observable size; the total mass of the cloud is estimated to be of the order of 1/10 to 1/100 of that of the earth. Through the action of the stars fresh comets are continually being carried from this cloud into the vicinity of the sun.”

Jan Oort (1900–1992) Dutch astronomer
