Pluto is smaller than Earth’s moon. Should our moon be a planet too?
Pegajace@lemmy.world 1 year ago
No, because size is not what makes a moon a moon. Our Moon is a moon because it directly orbits a planet, not a star. Charon is massive enough relative to Pluto that the former does not directly orbit the latter, but instead they both orbit a common barycenter located between them, making them a binary planetary system.

Does our moon independently orbit the sun?
Zellith@kbin.social 1 year ago
The barycenter between earth and the moon is within the earths crust. The barycenter between charon and pluto is outside of plutos surface. For those who dont understand, this means that the center of gravity between the earth and moon is INSIDE the earth. So the moon orbits a point within the earth. Not so with the charon pluto system. Both worlds orbit a point in space.

Gaia and Selene are double planets. Change my mind.

I hate when science headlines try to make shit seem all mysterious for clickbaits. Those are just the blood temples. We’ve known about them for decades. It’s not like a whole thing.

it always kinda bugs me that people lose their minds over Pluto but can’t name even one of the other four dwarf planets in our solar system

Ceres, Eris, Makemake, and I don’t remember. But I don’t think Pluto is a planet

Is Phobos one? They call that a moon and it’s nothing more than a pebble.
SupraMario@lemmy.world 1 year ago
That’s no moon…

I’ve never stopped believing in you, Pluto ❤️

Nothing compared to the bruises on Uranus.

How can you call yourself a grown up and you can’t even clean your orbit?

Those are just the seas of blood.

Wanna go explore them? I got this cool submarine for you.
