Most astronomers already call Ceres a "dwarf planet"

2:15 This visualization is NUTS!

i liked the thumbnail with nuts better then the one with actual planets and asteroids

the discovery of Ceres is itself a great story, worthy of a video.
It had been discovered by an Italian astronomer, Giuseppe Piazzi, but then it disappaered behind the sun, and he could not find it anymore. C.F. Gauss used Piazzi's data, invented linear regresion and the error function (i.e., the "normal" or "Gaussian" distribution) and lo and behold found Ceres right where he predicted it.

1:27 interesting archaic use of the term "computer" in the 1912 article. Here, referring to a person who computes data, rather than a machine that does so.

Sad because Pluto was mentioned only a total of zero times
@
2:25 Wow this is an amazing demonstration with the nuts. What a simple and beautiful way to illustrate the idea!

I never thought about when we first discovered the asteroids are mainly homogenous. Great visual metaphor with the nuts and raisins!
@
3:21 "orbs" is hilarious 😭

When Pluto was demoted to dwarf planet, wasn’t Ceres also raised to dwarf planet? I think that’s the case, but I’m not positive.
@
0:10 well, that matches the origin of the word planet; it means 'wanderer' in greek, as in a star that moved rather than staying put. So the asteroids were planets before we really knew what they were.

"I'm tired of arguing about these classification videos grandpa!"

Minutephysics: WELL THAT'S TOO DAMN BAD!

Isn't Ceres already considered a dwarf planet, like Pluto?

Woah, the stop motion animation was incredible!
@
I prefer the categories "worlds" and "space rocks" 😆
@
And to confuse things even more the word "asteroid" means star-like. Because in a telescope they looked like point sources of light like a star. Whereas planets have a clear shape even in a small telescope.

Casually dropping a periodic table timeline at 1:20

The thumbnail is nuts

That use of fruits and nuts is a really good illistration, but probably took so long.
