Our planet Earth’s radius is estimated to be about 6371 kilometers, but I doubt that this matters to you. Since an average person has nothing to compare these scales and distances to, they can hardly imagine them accurately. They're so broad that it's difficult to comprehend them. But let's give it a shot.
Consider our Earth to be the size of a tennis ball, and reducing all other dimensions to a specified scale, we get the following illustrative figures: the Sun would be about 1 km away from the tennis ball and would appear as a sphere with a diameter of a five-story house. Isn't it impressive? But that's not all: our galaxy's biggest stars have a diameter of around 2500 times that of the Sun. In our case, such a star will have the size of 3 diameters of the actual size of the Earth! Please keep in mind that the Earth is the size of a tennis ball! Nevertheless, even on such a small scale, the distance to the closest star is difficult to comprehend since it is around 220 thousand kilometers or roughly half of the distance to the Moon.

Came here through the recommendation of Mr Scientific

[shre_sg]

I enjoyed it even more than watching interstellar ❤️, great work 🔥

[juggernog]

This dude taught me more than school so far and that’s a good thing

[wskinnyodden]

Dear lord, Astronomist??? Really???? ASTRONOMERS!

[zoomzoom]

Thank you for these channels, for yrs I’ve wanted to learn about what we have above us our school never teaches anything like this. I’m 54 and I’m amazed on what a beautiful stunning planet we live on but men ruin it by drilling and stuff. I’m pretty sure we have aliens visiting our planet to see what damage we have done to it

[lifewiththekids]

Thank you Mr.Scientific, awesome recommendation

[josephshealey]

Great content. I was unaware of the channel . I'm sure there are other fans of space vids that don't know about the channel, it deserves way more views. Thank you

[howtodoit]

No humanity ever considered the earth the center of the universe it was just the Europeans.

[wskinnyodden]

JOVIAN SYSTEM! For feck sake call things by their PROPER NAMES!

[cleander]

Why did you say most likely Venus has no life? Isn’t that true scientists think there might be life in Venus clouds?

[freavon]

Who else came here from mr scientific???
Oh goddd how many me will come down

[abidhossain]

Stars are born in dense perseus molecular cloud, all stars likely form initially as binaries within dense core. These systems then either shrink or break apart within a million years. Based on this model, the sun's sibling most likely escaped and mixed with all the other stars in our region of the Milky Way galaxy. Our sun is unique in the Universe in terms of life. And if this uniqueness exists anywhere else then it would be best only in the twin siblings of the unique sun. Because of, as a twin they are made of the same kind of material and about the same size. If we find our sun's twin, only then we may find another planet with habitable atmosphere &/or existence of life.

[karim.mmmmmmm]

Yeah yeah we went to the moon in 1960 and here we are 2022 and we never went back again .. I just wonder why ..I'm sure people were told back then that in 2022 you would be spending your weekends on the moon ..

You only have 700 subs. You totally deserve more! Update- you only make videos for a month so that is great progress

[kevingreen]

I could find life tomorrow at either Area51 or Dulce base, simples, or skinwalker ranch

[beachbum]

Thanks to the experts at NASA, MIT, and Smithsonian, and the people at Area 51, we now KNOW that there is life on other planets, and we now KNOW what is contained in those "mysterious signals". On some far away planet, their car warranties are getting ready to expire! 😆

[Fylo-Kalist]

No. Right out of the box you lost me. You say "Our Earth and Sun are not as special as we thought about them", though any astronomer worth their weight will say our system is very unique compared to what they observe. Our Sun is extremely tame, producing far fewer flares than what we observe. Our Sun is not a binary and we presume about 85% are. We don't have super Earths. We don't have hot Jupiter's. Sigh. You also say there are "millions of planets just like ours". What!? That is an absolute assumption on your part and to say it as if it is fact...well you know what they say about assumptions. We have found something in the ballpark of 24 planets that fall in the habitable zone (none confirmed to be like ours) and around 4000 exo's in total. Are there millions, probably. Can you definitively name one that is just like ours, no you can't. I'm not even 30 seconds into the video and i feel like a middle schooler wrote the script. This is such a fun subject. Please don't ruin it with main stream media like sound bites that are absolute assumptions and falsehoods. It just makes uneducated people repeat the same thing which makes them look dumb and that's not very nice.

[SilentHendo]

None of us are special we're just specs of dust here for a short meaningless amount of time for no reason

[KnowledgeTVIndiaOfficial]

Here after Mr Scientific.
Btw Awesome video 🤩✨
