Every 25thousand years.. the next time will be in 2012
They never did. In all the solar systems history, all 8 planets never alighned in a straight line
the order of the planets starts with mercury, then Venus, then earth, next is mars, then Jupiter, after Saturn is Uranus. Pluto is not a planet, its a dwarf star.
To start, hopefully my solar system is the same as yours. There is no definite answer depending on how perfectly aligned you are asking. There was an alignment of sorts with 5 planets and the moon May 5th, 2000. The next one of those will happen in 2040. Including all the planets and a near perfect to perfect alignment, it's in the millions of years to trillions of years. For better information check out below:
No. The planets CANNOT all "line up", because they all orbit in slightly different planes. We occasionally see one or two planets line up, but never more than three at once.
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.

the planets align every millenia
Absolutely not at all. Apart from the fact that the planets never align exactly anyway.
A syzygy
When all planets align.
HURR durr hurr
Never.
in a line
Then it will look quite spectacular.
there are 8 planets namely mercury, venus, earth, mars, jupiter, saturn, uranus and neptune.
the alignment of the planetS: jupiTer, satUrn, rP900, and M30. It coulD also align with the order of the sun rays.
