Well actually considering the fact that the planets of the solar system all orbit on partially different inclinations with different rotations, also considering their apparent size, it would be impossible for the planets to align, and it will take so long to do such an alignment that the next time the planets will even be in the same part of the sky is May 6, 2492. Plus, the alignment of the planets is not in any way particularly special, as their effect is barely multiplied by their alignment. Doing such a thing might cause the combined effect of maybe 0.000005 less pounds of gravity on Earth- but even that's being generous..
Goodnight buddy ^^
And why'd you call me Steve xD
It would take a while to explain.
