In the same way there are binary star systems, could there be planets with moons of the same size or almost the same size as themselves?

See the Pluto and Charon system for an example.

I know I'm late for the questions but I love how we keep comparing these exoplanets to our own by saying a "Jupiter" " like planet or a "mercury" like planet. It seems like our solar system has a nice array of all different kinds of planets but is there a different type of planet that we don't have an example of in our system that could be orbiting other stars.

The Oort cloud is a hypothetical loose sphere of icy bodies left over from the formation of the solar system which orbit out sun. It is the explanation for the origin of a lot of comets.

We don't know enough about the solar wind to even say what shape it is. It could be a sphere, it could be compressed on the "forward" side of our sun in relation to it's motion through the galaxy, or it could even have a very long tail like a comet.

Regardless, Objects in the Oort routinely cross our "bubble".

If u cant form a planet inside the system maybe they came from outside. OR. Wizards did it.

[Andrew Planet]

Byeee!

[Michael Jobin]

Oort cloud is what we are passing threw.

[Kalle Centergren]

is the orth clowd outside the "bubble" that ouer sun blows around itself?

[Abraham Samma]

What is can we look forward to after Kepler?
