Uranus & Neptune: Crash Course Astronomy #19
About | Information | History | Online | Facts | Discovery
Today we’re rounding out our planetary tour with ice giants Uranus and Neptune. Both have small rocky cores, thick mantles of ammonia, water, and methane, and atmospheres that make them look greenish and blue. Uranus has a truly weird rotation and relatively dull weather, while Neptune has clouds and storms whipped by tremendous winds. Both have rings and moons, with Neptune’s Triton probably being a captured iceball that has active geology.

"Ur anus got whacked... HARD"

"I'd avoid breathing through your nose at ur anus"

Why not make separate video for Uranus and Neptune..
-
I have a project on planets I picked Uranus does anyone know how hot uranus is and how does it look inside
youranusURANUS -
your vids are very informative. you deserve more views.
-
uranus is my favorite planet. your anus is not.
-
Call me imature, but I couldn't watch this episode with a straight face even if my life depended on it.
-
+Crash Course I have a question. Some of my sources say that if you weigh 100 pounds on Earth, you will weigh 119 pounds on Neptune. Other sources say you will weigh 114. What is it? Also, how many rings does Neptune have? Some sources say 9 while others say 6.

I'm distracted by your forearms
-
Phil your videos are great: educational, smart and really well narrated. Thank you.
-
Uranus "danse hot and under a lot of pressure"? according to every single easily available source, including nasa website mean SURFACE temperature is ~ −197 °C, while its surface gravity is very very similar to earths while being much much bigger, means NOT so dense, NOT so under pressure, and not hot at all.

Diamondberg...
Really sounds like a jewish surname to be honest. :D -
So... what you are saying is we shouldn't go and sniff Uranus?
-
giant anus in the sky liging farts on fire!

uranus is a pretty planet, but we humans had to ruin it by giving it's shitty(litertrally) name.
first glance at your shirt i thought it was weed not coconut trees... -
Today is your last chance to take back our country. Today we can crush and beat the corrupt establishment by electing Donald Trump. We must beat Hillary who is funded by wall street and the Saudis and elect a man that isn't bought and someone who will bring real chance to Washington.
You may not agree with everything he says and he has said some stupid things over the years but this movement is much more important than words. We won't have another election like this, this is the only time we have a chance to beat a corrupt crooked candidate (Hillary) and elect someone who will put America First.
Please go out and vote today or you will regret it your entire life.
