"Venus is the planet that's closest to the Earth." - That is, of course, it's the planet that passes closest the Earth, though what planet is closest to us at any given time can be Mercury, Venus, or Mars depending on how the planets are aligned. Here's something interesting though: on average, the closest planet to us is... Mercury! That's because it never gets as far away from us as Venus or Mars. So stump your friends with the trick question: "Which planet, on average, is closest to Earth?"
That was the very first thought that popped into my head when he said that. And, adding to what you've mentioned - Mercury is, on average, the closest planet to *every other panet* in the solar system. But, in fairness to Dave, these results were first published around early 2019, after this video was made. Here are links to one of the articles and the associated simulation: physicstoday.scitation.org/do/10.1063/PT.6.3.20190312a/full/ th-cam.com/video/GDgbVIqGADQ/w-d-xo.html
About 50 km above the surface, Venus is actually very Earth like, with temperatures and pressures akin to those on Earth! The nasty 92 bars of atmospheric pressure and 440C temperatures only exist on the ground on Venus, slightly above the clouds however, is a completely different story. With Earth like gravity, pressures and temperatures, Venus at about 50 km up is the most Earth like place in our solar system other than Earth itself, cloud colonies could exist in the venusian atmosphere. These towns could take advantage of the ample solar energy available at Venus, much more than that available on Earth or Mars. Now, protective suits would be required when outdoors just above Venus clouds, but no pressurizaton would be needed!
It would be a terrible death to fall over the side and be simultaneously dissolved, crushed and scalded alive before hitting the ground. You would never recover the body.
I don’t think many people realize that Uranus and Neptune are also both very similar in sizes just like earth and Venus are, except Uranus is just slightly bigger then Neptune
Aaah, I was hoping you were going to touch on the newly discovered organic compounds present in the upper atmosphere and the concept of visiting Venus using a floating platform which is above the sulfuric acid clouds, moderate temps in the 70's, and air pressure comparable to sea level on Earth. Maybe next time ..
Hi professor. Can you do a video to explain the internal nucleophilic substitution for allylic and vinylic systems..it must have practical solved problems... Please do I'm waiting for you❤️❤️
I suppose the atmosphere in Venus was also studied and better understood in the 70's - 90's. That would explain some science fiction novels prior to this period where Venus was inhabited or visited by humans :)
In addition to being the goddess of love, sex and fertility, Ishtar was worshipped as a goddess of war, justice and political power. After the Greeks adopted this goddess as Aphrodite, many of these traits started to fade out of her myths, but you can still see traces of her military side in stories such as the Iliad. It really makes Venus's hellish state appropriate, in my opinion.
Dave, when you say there are competing theories as to why Venus rotates opposite of the other planets, are these "theories" in the scientific sense or more competing hypotheses? Can you please explain?
the sulphuric acid clouds why havent they been neutralized yet by the ground which would be made up of sillicates a d yes the ground might have a thin surface layer of sulphites and sulphides but the volcanic activity would bring up new silicates
This is so minor and doesnt matter but as an ancient history nerd i have to. The Romans did not copy the greek pantheon, the greeks and romans were both indo European people, their pantheons similarities were a result of having the same origin point of whatever the proto indo European pantheon was. So aphrodite was not renamed venus, aphrodite and venus evolved from an earlier goddess at similar times.
Hey Dave, the videos you make are really informative & I love the topics you choose as well but there's something missing. I can't pinpoint what exactly that is but the videos kinda seem dull, perhaps you could see the scishow vids to see what they are doing different as they have the same presentation style as you. In the end just want to see your channel grow 🤗
I think you are referring to the flashy animations, wild gesticulations, rapid cut style, grab bag trending topic selection, and forced humor that is found in a wide variety of edutainment content, which many people have come to expect only because it is so prevalent. I very deliberately do not engage in any of that, as I believe it takes away from the educational merit of the content. I think it hinders the act of conveying information, and as that is all I care about, I have opted for a more minimalistic and curriculum-based approach. But to each their own!
1:44 It's 461 celsius to the rest of the world.
thanks
Thank you.
Thank you xd
Eat me
Kelvin and Fahrenheit .... leaving poor Celsius out of your presentation : (
oh you can get C real quick in your head from K
Kelvin is just Celsius with a different starting point. Kelvin is Metric.
Just -273 what's so difficult

CGP?
@@asylumskp4391 I hope that one day we can visit Venus.
I learned this through an excellent video by CPG Grey.
You stole that from CGP Grey
Love these videos so much. I have always been in love with space. I can never get enough information on outer space
Earth's evil twin: Venus
Professor Dave. You really are a master of all trades.
@Yo XD what😂
Awesome video! I loved it!
I love the way that he calls them tutorials
your vids are great

Just protection from all that sulfuric acid. Nothing major ❤️😋

Professor Dave is a legend. Thank u, prof!!!
for the last few weeks or so I've been almost always watching Venus in the morning sky

I think I talk about that stuff in the later videos on exoplanets and and astrobiology and what not. These ones are just the facts about the planets.
@@ProfessorDaveExplains Cool cool, thanks for replying, didn't expect that!

james clerk maxwell! great physicist.
@@ProfessorDaveExplains Ah yes. He established a famous house if I recall correctly. 😁

If we are children of earth, does this mean venus is our aunt?
You made a cool video
Vex on the field!
So his sister is stress cuz its hot at venus
Hi professor! I am from India.will you please make a video on rotational plane of moon with a 3D effect?It will be very grateful for me.please
I was thinking Venus is the evil sister
I thought you died in Bolivia :/
Earth have sister name venus and earth have brother name mars
guess they called it “earths sister” because she’s hot

can someone write 4 facts for me? thats on this video
@Alex Roz Because of personal business irl
Evil twin
ok but where deos ut say the asus suttff\\ jelel me right nwi or i wjkk not hestittate to opull out a mace oin uyour chikdlfren
Who tf measures in kelvin? Like who are you tryna impress??
Scientists. Scientists measure in Kelvin.
Wait... inferior planets???? WHAT hahahahahahahhahaha
Mercury is boring
