Only 4 planets, still not bad.

What planets are visible during the next alignment of planets? The next planetary alignment takes place on April 4, 2024. It will feature four planets – Venus, Neptune, Saturn, and Mars. The planets will align in the morning sky. Venus, Saturn, and Mars will be visible to the naked eye, but you'll need a telescope or high-powered binoculars to see Neptune. Let's take a closer look at the conditions for observing the planets.

I think the author was confused. Apparently it was a couple years ago.

And I missed it, it was proably raining in this shithole anyway.

Lol, the planets do lay on a plane. But its tilted.

One of the big mysteries, which can easily be explained by planet 9.

Today, we’ve mapped out the orbits of the planets to incredible precision, and what we find is that they go around the Sun — all of them — in the same two-dimensional plane, to within an accuracy of, at most, 7° difference.

In fact, if you take Mercury out of the equation, the innermost and most inclined planet, you’ll find that everything else is really well-aligned: the deviation from the Solar System’s invariable plane, or the average plane-of-orbit of the planets, is only about two degrees.

The tilt of the solar system's orbital plane has long befuddled astronomers because of the way the planets formed: as a spinning cloud slowly collapsing first into a disk and then into objects orbiting a central star.

Planet Nine's angular momentum is having an outsized impact on the solar system based on its location and size. A planet's angular momentum equals the mass of an object multiplied by its distance from the sun, and corresponds with the force that the planet exerts on the overall system's spin. Because the other planets in the solar system all exist along a flat plane, their angular momentum works to keep the whole disk spinning smoothly.

Planet Nine's unusual orbit, however, adds a multi-billion-year wobble to that system. Mathematically, given the hypothesized size and distance of Planet Nine, a six-degree tilt fits perfectly, Brown says.

Assuming you believe in that kinda thing.

Also in a picture in one of the articles I linked in the other comment, you can see that it doesnt line up like a stick pointing out from your point of view, but horizontally across the skyline instead. Need a telescope to even see the fainter ones.
