So would we be able to see it?

You can see it whether or not it's aligned with solar plan

Awesome

Here's my photo of Pluto taken just a few days ago using an 8 inch diameter telescope and a very sensitive camera. Pluto is very far away and very faint. Only fairly large telescopes would allow you to see it visually, and even so, it's hard to pick out.https://twitter.com/GrumpyOldAstro/status/1015922010134753280 …

Great photo! Yeah, it must be indeed quite difficult to spot it

Welcome back Pluto!!
#BringItHome -
Well at least something is comin home
-
Actually, it's heading out towards the aphelion now so "Goodbye Pluto!"

You don't need to tell England that

Why did Pluto cross the plane? To get to the other sidereal.

I don't fully understand what that means but I'm a bit happier than I was before reading this..
-
The orbits of the 8 planets are nearly in the same plane, while Pluto's orbit is significantly inclined in comparison, as shown on the image. Yesterday, Pluto was at one of the two points of its orbit that intersect the plane of the planets' orbits.
-
More specifically, yesterday the Sun, the Earth and Pluto were aligned. It can only happen when Pluto is at one of these two positions on its orbit.
-
Does this mean at some point theoretically Pluto could smash into Neptune?
-
The odds are very low but there's always a chance
-
No. The 3:2 mean-motion resonance between the two objects (i.e. Pluto makes exactly two orbits when Neptune makes three) prevents any close approach between them. The minimum distance between Pluto and Neptune is ~18 times the Sun-Earth distance, i.e. ~2.7 billion kilometers.

Nice science math dude

Why does it take 87 years one way and 161 the other? Looking at the image it does appear that more of Pluto's orbit is below the plane than above, so maybe that arc is longer, but I'm not sure if that's an illusion caused by the graphic. Thanks in advance! <3
-
Yes, its orbit is lopsided. It’s also closer to the sun than Neptune for only 20 years of its 248-year orbit. All of the planets have elliptical orbits rather than circular, and some are more stretched out than others.
-
I knew that most orbits are elliptical, but I forgot that orbits don't have to be "centered" on the thing they're orbiting. Now that I think about it though, I seem to remember seeing a graphic of something that has an extremely elongated, lopsided orbit. Thanks for the reminder!
-
You’re welcome! And if you think of an ellipse as a circle with two centers, how far “off round” the ellipse is will be determined by how far apart the centers are. For a planet, I believe the star it orbits has to be at one of those centers.
-
Oh very cool! I know objects orbit their "mutual center of gravity", which for most stuff in our solar system is inside the sun. I think maybe Jupiter's COG w/the sun is slightly above Sol's surface? But that just describes what's causing the physics, not the orbit's shape.
