"Twentieth century Belgian astronomer Jean Meeus asserts that the orbits of all nine planets were within the same 90% arc of the solar system on 1 February 949. The next time it is thought this will occur is on 6 May 2492."

What is meant by "90% arc". Should this be 90 degree arc? A 90% arc would be most of the solar system and does not seem too rare.--35.8.153.13 19:55, 31 July 2006 (UTC) John French.

Agreed. I've done an edit, which includes changing the word "orbits" to "positions". If all the planets lined up within 9 (nine) degrees of each other, it would be an interesting sight, so I similarly don't understand what the fuss was about. EatYerGreens 15:28, 28 February 2007 (UTC)
