They never did. In all the solar systems history, all 8 planets never alighned in a straight line
The last time all of the planets aligned in a straight line was 561 BC. This phenomenon is known as a grand conjunction, where all the visible planets appear to align along the zodiac during a short period.
Every 25thousand years.. the next time will be in 2012
All the planets in our solar system never truly align perfectly due to the varying orbits and speeds at which they travel. The closest they come to alignment is known as planetary alignment, and the last time a rough alignment occurred was in 2010, but a perfect alignment is extremely rare.
The planets did not align per say; however they did come into a state of Syzygy ( look on wikipedia; and commit to memory, because its great for Scrabble). On that date (3/10/1982), all 9 planets came with in 91 degrees (this is debated, I've heard as much as 95 degrees) of alignment, on the same side of the sun. This is a very rare event, and will only happen once in the length of human kind. We would have to be pretty lucky to last another million or so years. Looking at it from a purely statistical standpoint, all 9 planets will never perfectly align in the same plane. March 10th 1982 is the closest we will ever get.
Planets do not align in the sense of forming a straight line. While planetary alignments can occur, they are not rare and do not have any significant impact on Earth. The last general alignment visible from Earth occurred in 2000, and the next similar alignment is predicted in 2467.
the planets align every millenia
Align the Planets was created on -20-05-04.
last time i heard it was sometime in late February early March

Yes, it is theoretically possible for all the planets in our solar system to align, but it is extremely rare due to the different orbits and speeds at which they move. The last time all the planets aligned in a straight line was in 561 BC, and the next alignment of all the planets is not expected to occur for several centuries.
A syzygy
It is extremely rare for all of the planets in our solar system to align perfectly in a straight line due to their individual orbits and distances from the sun. The last time a near-perfect alignment of the planets occurred was in 561 BC, and there is no scientific evidence to suggest that such an event will happen again in the foreseeable future.
HURR durr hurr
Then it will look quite spectacular.
in a line
Never.
the alignment of the planetS: jupiTer, satUrn, rP900, and M30. It coulD also align with the order of the sun rays.
