Here's why:
* Orbital Planes: The planets in our solar system orbit the Sun in slightly different planes, like a slightly tilted frisbee.
* Elliptical Orbits: Planets don't orbit in perfect circles, but in slightly elliptical paths.
While there are occasions when planets appear to be relatively close together in the sky from our perspective, they never line up in a perfect line.
What can be seen:
* Conjunctions: These are events where planets appear close together in the sky from our perspective. While not a perfect alignment, they can be visually stunning.
If you're interested in learning more about planetary alignments, I recommend checking out resources from NASA or reputable astronomy websites.
